Question

please tell me step by step please ​

Answer 1

Explanation:

i.

$p(x) = (x + 1)(x - 2)$

If x = -1,

$p( - 1) = ( - 1 + 1)( - 1 - 2) = 0( - 3) = 0$

If x = 2,

$p(2) = (2 + 1)(2 - 2) = (3)0 = 0$

Since the answer in both cases is 0, x = -1 and 2 are the zeroes of the polynomial.

ii.

$p(x) = x {}^{2}$

If x = 0,

$p(0) = 0 {}^{2} = 0$

Since the answer is 0, x = 0 is the zero for the polynomial.
