Question:

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

A. - 3 (x + 3) B. 3 (x + 3) C. 3 (-x - 3) D. - 3 (x - 3)

Answer:

Option A and option C

Two different ways of factoring - 3x - 9 is 3 (-x - 3) and - 3 (x + 3)

Solution:

Given expression is - 3x - 9

We have to find two different ways of factoring this expression

Factoring: Finding what to multiply together to get an expression. It is like "splitting" an expression into a multiplication of simpler expressions.

Factoring a polynomial involves writing it as a product of two or more polynomials

⇒ - 3x - 9

Taking 3 as common term,

⇒ - 3x - 9 = 3 (-x - 3)

So Option C is correct

Also we can take - 3 as common term,

⇒ - 3x - 9 = - 3 (x + 3)

Thus Option A is also correct
