Question

find the value if x=-3
$p(x) = x ^{3} + x ^{2} - 9x - 9$
​

Answer 1

Given,

$p(x) = {x}^{3} + {x}^{2} - 9x - 9$

If x = (-3); then,

$p(x) = p( - 3) \\ = { - 3}^{3} + { - 3}^{2} - 9( - 3) - 9 \\ = - 27 + 9 + 12 - 9 \\ = 21 - 36 \\ = - 15$

HOPE THIS COULD HELP!!!

Answer 2

Answer:

hii.

Step-by-step explanation:

given equation here..

p(x)= x^3+x^2-9x-9.

now put here..

x=-3

then ,

p(-3)= (-3)^3+(-3)^2-9*(-3)-9

p(-3)= -27+9+27-9

p(-3)=0.

I hopes its helps.
