Which of those choices shows the 4 factored out?

Answer 7

What do u mean by factored out ?

Answer 8

So say you had 8x + 4.

4 is common to both 4 and 8, so when you factor it out it looks like 4(2x+1).
When you multiply 4 and 2x, you get 8x, and when you multiply 4 and 1, you get 4.

Answer 9

The 4 was factored out (it's outside the parentheses).
