Question

Which values ​​of xwould make a polynomial equal to zero if the factors of the polynomial were (x + 4) and (x + 8)? O A. 4 and -8 O B. 4and 8 O C. -4 and -8 O D. -4 and 8

Answer 1

-4 and -8

Explanation:

Set each of the 2 factors = to 0 and solve for x:

x + 4 = 0 ↔ x = -4

x + 8 = 0 ↔ x = -8

The x-values -4 and -8 are the roots (zeros) of a polynomial whose factors are (x + 4) and (x + 8).
