Answer 2

Answer:

1. If x + y = 12 and xy = 32, Find the value of x2 + y2.

2. If 3x + 2y = 12 and xy = 6, find the value of 9x2 + 4y2.

3. Write the following cubes in the expanded form:

(i) (3a + 4b)3

(ii) (5p – 3q)3

4. If find the values of each of the following:

(i)

(ii)

5. If then evaluate

6. If a + b + c = 15 and a2 + b2 + c2 = 83, find the value of a3 + b3 + c3 – 3abc.

7. Factorize:

(i) 6ab – b2 + 12ac – 2bc

(ii) 9(2a – b)2 – 4(2a – b) – 13

8. If x3 + ax2 – bx + 10 is divisible by x2 – 3x + 2, find the values of a and b.

9. Using factor theorem, factorize each of the following polynomials:

(i) x3 – 6x2 + 3x + 10

(ii) 2y3 – 5y2 – 19y + 42

10. Which one is not a polynomial
