Answer:
Step-by-step explanation:
Both terms of the expression have something in common. This "something" is known as the greatest common factor, or g.c.f., in math.
4x and -12 have a g.c.f. of 4, so that's what we factor out.
First, we divide both 4x and -12 by 4. We obtain
x-3
Put parentheses around x-3. You'll see why in a sec!
(x-3)
Now, put 4 outside the parentheses (4 is the g.c.f.)
4(x-3)
