(a) 10

(b) -10

(c) 5

(d) -5

## Answers

(b)**Q.2. If the zeroes of the quadratic polynomial x ^{2} + (a + 1) x + b are 2 and -3, then**

(a) a = -7, b = -1

(b) a = 5, b = -1

(c) a = 2, b = -6

(d) a – 0, b = -6

## Answers

(d)**Q.3. The zeroes of x ^{2}–2x –8 are: **

(a) (2,-4)

(b) (4,-2)

(c) (-2,-2)

(d) (-4,-4)

## Answers

(b) x^{2}–2x –8 = x

^{2}–4x + 2x –8

= x(x–4)+2(x–4)

= (x-4)(x+2)

Therefore, x = 4, -2.
