C.
(x+4) and (x-8)

(x + 4) and (x+8)

Answer 1

C. (x+4) (x-8)

Explanation:

Take the graph for example both x values are -4 & positive 8

Answer 2

C. (x+4) and (x-8)
this is because when the sign is positive, then it goes to the left and when the sign is negative you go to the right. On the graph the x-intercepts are at -4 and 8 so you can switch the signs on them to figure out the factors
