Answer:
Below is all the info you need! ^^
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)
