What are the zeros of the polynomial function

f (x) = x^3-2x^2-8x

a - 4,0,2

b - 4,2

c - 2,0,4

d - 2,4

The zeros are 0, - 2, and 4.

Step-by-step explanation:

Factor equation into x (x+2) (x-4) = 0

Solve.

x+2=0

x=-2

x-4=0

x=4

and do not forget the x in the front, which needs no solving, as it equals zero.

x=0
