Question

-4x + 12
Factor the common factor out of each expression.

Answer 1

Answer: 4(-x+3)

Explanation:

Hii, do you need to factor the expression -4x+12? No problem! (:

Note that both -4x and 12 have something in common. This "something" is known as the greatest common factor, or g.c.f.

The g.c.f. of -4x+12 is 4.

To factor it out, we first need to divide -4x+12 by 4.

-x+3 is what we obtain

Next, we put parentheses around -x+3

(-x+3) is what we obtain

Finally, we put 4 outside the parentheses

4(-x+3)

Answer 2

4 (3 - x)

Explanation:

Take the common factor 4 out.

`4(`

Then divide the numbers inside the expression with the common factor

`4( ( - 4x)/(4) + (12)/(4))`

`4( - x + 3)`

You can rewrite it as:

`4(3 - x)`

Hope it helps!
