What are the zeros of the polynomial function f(x) = x3 − x2 − 20x?

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
