Question

Find the zeros of quadratic polynomial p(x)=(x+7)(x-9)

Answer 1

p(x) = (x+7) (x-9)

p(x) = 0

(x+7) (x-9) = 0

x+7 = 0 ; x = -7

x-9 = 0 ; x = 9

Therefore,the zeroes of the polynomial are -7 and 9

Hope it helps....

Answer 2

p(x) = (x+7) (x-9)

(x+7) (x-9) = 0

x = -7 , x = 9

Therefore,the zeroes of the polynomial are -7 and 9
