Use the zero product to determine the zeros of y = (x + 4) (x - 10) (x - 7)

-4 10 7

-4,-10,-7

4, 10,7

4,-10,-7

x = - 4, x = 10, x = 7

Step-by-step explanation:

To find the zeros let y = 0, that is

(x + 4) (x - 10) (x - 7) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 10 = 0 ⇒ x = 10

x - 7 = 0 ⇒ x = 7
