Question

find all the zeros of polynomial f x is equal to x cube + 13 x square + 32 X + 20 if one zero is -2​

Answer 1

Answer:

$\huge\underline\mathbb\red{AnSwEr}$

Step-by-step explanation:

f(x)=x³+13x²+32x+20

f(-2)=(-2)³+13(-2)²+32(-2)+20

=-8+13(4)-64+20

=-8+52-64+20

=-8+52-44

=-8+8

=0

hence proved it

Answer 2

f(x)=x³+13x²+32x+20

f(-2)=(-2)³+13(-2)²+32(-2)+20

=-8+13(4)-64+20

=-8+52-64+20

=-8+52-44

=-8+8

=0
