Answer:

Below is all the info you need! ^^

Step-by-step explanation:

Note that both -63 and -7x have something in common. This "something" is known as the greatest common factor (g.c.f.).

The g.c.f. of -63 and -7x is -7, so that is what we factor out.

Let's divide both -63 and -7x by -7 first. We obtain

9+x, because if we divide a negative number by a negative number, we obtain a positive number.

Now we put parentheses around 9+x.

(9+x)

Next, we put -7 outside the parentheses.

-7(9+x)
