Question

select the factored form of this expression.
-36 - 48x
after you pick your answer press go.
a. -48(12 - x) b. -12(3 + 4x)
c. -36(1 + 12x) d. -12(3 - 4x)
e. not factorable

Explanation:

Step1: Find GCF of -36, -48

The greatest common factor of 36 and 48 is 12, so GCF of -36 and -48 is -12.

Step2: Factor out -12 from expression

$$\begin{align*} -36 - 48x &= -12 \times 3 + (-12) \times 4x \\ &= -12(3 + 4x) \end{align*}$$

Step3: Match with options

Compare the result to given choices.

Answer:

B. $-12(3 + 4x)$
