Answer:
4(x+3)
Step-by-step explanation:
In this example, both terms, 4x and 12, have something in common. In math, this is known as the greatest common factor (g.c.f.)
The g.c.f. of 4 and 12 is 4, so that's what I'm going to divide both 4x and 12 by.
Upon doing so, we obtain
x+3
Put parentheses around x+3. You'll see why soon.
(x+3)
Now we put 4 outside the parentheses.
4(x+3)
See, the parentheses indicate that we multiply 4 times both x and 3.
