Question

If the factors of a polynomial are x + 8 and x + 4, what values of x make that polynomial 0?

A. 8 and -4
B. -8 and 4
C. -8 and -4
D. 8 and 4

Answer 1

-8 and -4

C is answer

Answer 2

Given the factors, the polynomial can be expressed as,
(x + 8)(x + 4) = 0
The factors may be individually taken account,
x + 8 = 0 ; x = -8
x + 4 = 0 ; x = -4
Thus, the values of x are -8 and -4. The answer is letter C.
