determine the value(s) of b in order for 2x + bx - 12 to be factorable. Is there more than one possibility? How many? Explain your reasoning or show how you arrived at your solution(s).

expression #3 is not equivalent. the others are.

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
