Important Polynomials Questions For Class 9- Chapter 2 (With Solutions)

Some important questions from polynomials are given below with solutions. These questions will help the 9th class students to get acquainted with a wide variety of questions and develop the confidence to solve polynomial questions more efficiently.

1. Give an example of a monomial and a binomial having degrees of 82 and 99, respectively.

An example of a monomial having a degree of 82 = x 82

An example of a binomial having a degree of 99 = x 99  + x

2. Compute the value of 9x 2 + 4y 2 if xy = 6 and 3x + 2y = 12.

Consider the equation 3x + 2y = 12

Now, square both sides:

(3x + 2y) 2 = 12 2

=> 9x 2 + 12xy + 4y 2 = 144

=>9x 2 + 4y 2 = 144 – 12xy

From the questions, xy = 6

9x 2 + 4y 2 = 144 – 72

Thus, the value of 9x 2 + 4y 2 = 72

3.    Find the value of the polynomial 5x – 4x 2  + 3 at x = 2 and x = –1.

Let the polynomial be f(x) = 5x – 4x 2  + 3

Now, for x = 2,

f(2) = 5(2) – 4(2) 2 + 3

=> f(2) = 10 – 16 + 3 = –3

Or, the value of the polynomial 5x – 4x 2  + 3 at x = 2 is -3.

Similarly, for x = –1,

f(–1) = 5(–1) – 4(–1) 2 + 3

=> f(–1) = –5 –4 + 3 = -6

The value of the polynomial 5x – 4x 2  + 3 at x = -1 is -6.

4. Calculate the perimeter of a rectangle whose area is 25x 2  – 35x + 12. 

Area of rectangle = 25x 2  – 35x + 12

We know, area of rectangle = length × breadth

So, by factoring 25x 2  – 35x + 12, the length and breadth can be obtained.

25x 2  – 35x + 12 = 25x 2  – 15x – 20x + 12

=> 25x 2  – 35x + 12 = 5x(5x – 3) – 4(5x – 3)

=> 25x 2  – 35x + 12 = (5x – 3)(5x – 4)

So, the length and breadth are (5x – 3)(5x – 4).

Now, perimeter = 2(length + breadth)

= 2(5x – 3 + 5x – 4) = 2(10x – 7) = 20x – 14

So, the perimeter = 20x – 14

5. Find the value of x 3  + y 3  + z 3  – 3xyz if x 2  + y 2  + z 2  = 83 and x + y + z = 15

Consider the equation x + y + z = 15

From algebraic identities, we know that (a + b + c) 2  = a 2  + b 2  + c 2  + 2(ab + bc + ca)

(x + y + z) 2  = x 2  + y 2  + z 2  + 2(xy + yz + xz)

From the question, x 2  + y 2  + z 2  = 83 and x + y + z = 15

15 2  = 83 + 2(xy + yz + xz)

=> 225 – 83 = 2(xy + yz + xz)

Or, xy + yz + xz = 142/2 = 71

Using algebraic identity a³ + b³ + c³ – 3abc = (a + b + c)(a² + b² + c² – ab – bc – ca),

x 3  + y 3  + z 3  – 3xyz = (x + y + z)(x² + y² + z² – (xy + yz + xz))

x + y + z = 15, x² + y² + z² = 83 and xy + yz + xz = 71

So, x 3  + y 3  + z 3  – 3xyz = 15(83 – 71)

=> x 3  + y 3  + z 3  – 3xyz = 15 × 12

Or, x 3  + y 3  + z 3  – 3xyz = 180

6. If a + b + c = 15 and a 2 + b 2 + c 2 = 83, find the value of a 3 + b 3 + c 3 – 3abc.

We know that,

a 3 + b 3 + c 3 – 3abc = (a + b + c)(a 2 + b 2 + c 2 – ab – bc – ca) ….(i)

(a + b + c) 2 = a 2 + b 2 + c 2 + 2ab + 2bc + 2ca ….(ii)

Given, a + b + c = 15 and a 2 + b 2 + c 2 = 83

From (ii), we have

15 2 = 83 + 2(ab + bc + ca)

⇒ 225 – 83 = 2(ab + bc + ca)

⇒ 142/2 = ab + bc + ca

⇒ ab + bc + ca = 71

Now, (i) can be written as

a 3 + b 3 + c 3 – 3abc = (a + b + c)[(a 2 + b 2 + c 2 ) – (ab + bc + ca)]

a 3 + b 3 + c 3 – 3abc = 15 × [83 – 71] = 15 × 12 = 180.

7. If (x – 1/x) = 4, then evaluate (x 2  + 1/x 2 ) and (x 4 + 1/x 4 ).

Given, (x – 1/x) = 4

Squaring both sides we get,

(x – 1/x) 2 = 16

⇒ x 2 – 2.x.1/x + 1/x 2 = 16

⇒ x 2 – 2 + 1/x 2 = 16

⇒ x 2 + 1/x 2 = 16 + 2 = 18

∴ (x 2 + 1/x 2 ) = 18 ….(i)

Again, squaring both sides of (i), we get

(x 2 + 1/x 2 ) 2 = 324

⇒ x 4 + 2.x 2 .1/x 2 + 1/x 4 = 324

⇒ x 4 + 2 + 1/x 4 = 324

⇒ x 4 + 1/x 4 = 324 – 2 = 322

∴ (x 4 + 1/x 4 ) = 322.

8. Find the values of a and b so that (2x 3 + ax 2 + x + b) has (x + 2) and (2x – 1) as factors.

Let p(x) = 2x 3 + ax 2 + x + b. Then, p( –2) = and p(½) = 0.

p(2) = 2(2) 3 + a(2) 2 + 2 + b = 0

⇒ –16 + 4a – 2 + b = 0 ⇒ 4a + b = 18 ….(i)

p(½) = 2(½) 3 + a(½) 2 + (½) + b = 0

⇒ a + 4b = –3 ….(ii)

On solving (i) and (ii), we get a = 5 and b = –2.

Hence, a = 5 and b = –2.

9. Check whether (7 + 3x) is a factor of (3x 3 + 7x).

Let p(x) = 3x 3 + 7x and g(x) = 7 + 3x. Now g(x) = 0 ⇒ x = –7/3.

By the remainder theorem , we know that when p(x) is divided by g(x) then the remainder is p(–7/3).

Now, p(–7/3) = 3(–7/3) 3 + 7(–7/3) = –490/9 ≠ 0.

∴ g(x) is not a factor of p(x).

10. Factorise x 2 + 1/x 2 + 2 – 2x – 2/x.

Solution:  

x 2 + 1/x 2 + 2 – 2x – 2/x = (x 2 + 1/x 2 + 2) – 2(x + 1/x)

= (x + 1/x) 2 – 2(x + 1/x)

= (x + 1/x)(x + 1/x – 2).

11. Factorise x 2 – 1 – 2a – a 2 .

x 2 – 1 – 2a – a 2 = x 2 – (1 + 2a + a 2 )

= x 2 – (1 + a) 2

= [x – (1 – a)][x + 1 + a]

= (x – 1 – a)(x + 1 + a)

∴ x 2 – 1 – 2a – a 2 = (x – 1 – a)(x + 1 + a).

Nice questions but little bit difficult make it easy to solve

I don’t got question 5, step x^3+y^3+z^3-3xyz=15(83-71) Why we subtracted 83-71??

We evaluated the value of xy + yz + xz, initially, which is equal to 71. Since, x^3 + y^3 + z^3 – 3xyz = (x + y + z)(x² + y² + z² – (xy + yz + xz)) [By algebraic identities] And x + y + z = 15, x² + y² + z² = 83 and xy + yz + xz = 71 So, if we substitute the values, we get: x^3 + y^3 + z^3 – 3xyz = 15(83 – 71) Please go through the complete solution for the answer.

The expression is x^3+y^3+z^3 = (x+y+z)(x^2+y^2+z^2-xy-yz-xz)

= (x+y+z){(x^2+y^2+z^2)-(xy+yz+sa)}

x^2 +y^2 + z^2 = 83, xy+yz+sa = 71 This is why 83 -71 is done

x + y + z = 15, x² + y² + z² = 83 And xy + yz + xz = 71 Now, Acc. To the question, x3 + y3 + z3 – 3xyz which is equal to = (x + y + z)(x² + y² + z² – (xy + yz + xz)) And these are given above So we subtract 83 – 71

because the formula is x^3+y^3+z^3-3xyz = (x+y+z)(x^2 + y^2 + z^2-xy-yz-zx) and we know x+y+z= 15 and x^2 + y^2 + z^2 = 83 and xy+yz+zx = 71 and -xy-yz-zx = -71 so we have putted the values on formula 15(83-71)

we found the value of xy+yz+zx so in the above step we take ‘-‘ as common and then xy+yz+zx so it will -71 then it is 15*12=180

This is so nice we can learn easily

wow! nice app

Fall 2024: important dates and deadlines for students.

As a student at the University of Iowa in the College of Liberal Arts and Sciences, please be mindful of these key dates and deadlines for the fall 2024 semester. 

Here are a few tips for staying ahead of important dates: 

• Create a calendar  or planner and mark down all the important dates and deadlines for your semester. 
• Set reminders  for yourself on your phone or computer marking upcoming deadlines. 
• Be aware of your course assignments to avoid the stress of missing a deadline. 
• Talk to your academic advisor  if you have any questions about important dates and deadlines.  

Four key dates and deadlines to keep in mind: 

Census date Monday, Sept. 9, 2024

The census date is the date for enrollment in a certain number of credits to be eligible for some scholarships and financial aid. If you do not meet the census requirement, you may have to pay more tuition or lose financial aid. Be sure to check with student financial aid for more information about your specific situation if you are changing your schedule. 

Tip: Keep track of your credit hours throughout the semester so that you do not accidentally fall below the requirement. 

Add or drop deadlines Several dates

Add/drop deadlines allow you to add or drop classes without penalty. After the first add/drop deadline, you will only be able to drop classes with a W grade, which will not affect your GPA. 

Tip : If your course does not meet for the full semester, the deadlines will vary. Be sure to check your  specific course deadline .

• Last day to drop without a W (full semester-length courses only): Monday, Sept. 9, 2024
• Last day to add without collegiate approval: Monday, Sept. 9, 2024
• Last day to drop (full semester-length courses only): Monday, Nov. 18, 2024
• Last day to withdraw from the entire spring 2024 semester: Monday, Nov. 18, 2024

Winter and spring registration  Nov. 11-Dec. 6.

It’s important to register for next semester’s classes as soon as you are eligible to ensure you get the classes you need for graduation.

Tip : Schedule an appointment with your advisor about a month before registration to plan your schedule. If you get notified about a registration hold, clear it as soon as possible.

• Meet with your academic advisor to be cleared for registration, if necessary 
• Spring 2025 schedule builder open: Monday, Sept. 30, 2024
• Early registration for winter begins: Monday, Nov. 11-Friday, Dec. 6, 2024
• Early registration for spring begins: Monday, Nov. 11-Friday, Dec. 6, 2024

Final exams  Dec. 16-20, 2024

Final exams are held at the end of each semester. They are typically not during your normal course meeting time. Be sure to check your syllabus.

Tip : Start studying for your final exams early! This will help you to avoid feeling overwhelmed and stressed during finals week.

• Last day of class before final exams: Friday, Dec. 13, 2024
• Final Exam Week: Dec. 16-20, 2024

Other important deadlines

Tip : Start working on your scholarship and graduate school applications early. This will give you plenty of time to gather all of the required materials and proofread your essays.

• Deadline to apply for Fall 2024 graduation: Friday, Oct. 4, 2024
• Midterm reports: Friday, Oct. 25, 2024
• Fall break: Nov. 25-29, 2024
