Answer 1

A, B, D, F

Explanation:

Answer 2

A, B, D, F

Explanation:

Given

f(x) = (x + 3)(x - 1)(x - 2)(x + 2)

To find the zeros let f(x) = 0, that is

(x + 3)(x - 1)(x - 2)(x + 2) = 0

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3 → B

x - 1 = 0 ⇒ x = 1 → F

x - 2 = 0 ⇒ x = 2 → D

x + 2 = 0 ⇒ x = - 2 → A
