Answer:
x = -1, x = -2 , x= 2
Step-by-step explanation:
First we factorise this cubic function :
(x+1)(x+2)(x-2) = 0
Using the law a×b×0 = 0
We know that to find the zeros we have to set each bracket equal to 0 :
x+1 = 0 OR x+2 = 0 OR x-2 = 0
x = -1 x = -2 x = 2
Hope this helped and have a good day
