What are two different way of factoring -3x-9? Select all that apply

Ghella [55]

Options:

A. –3(x + 3)

B. 3(x + 3)

C. 3(–x – 3)

D. –3(x – 3)

Answer:

A and C

Step-by-step explanation:

Given

$-3x - 9$

Required

Factorize

The options are not given; So, I'll answer on a general term

$-3x - 9$

Express -9 as -3 * 3

$-3x - 9 = -3x - 3 * 3$

Then factorize 3 out of the expression as:

$-3x - 9 = 3(-x - 3)$

Another way is to factor -3 out of the expression as:

$-3x - 9 = -3x - 3 * 3$

$-3x - 9 = -3(x + 3)$
