Which of the following is not a factor of 4x^2 + 12x?

a) x + 3
b) x
c) 3x
d) 4

C

Step-by-step explanation:

Let's try it

Take 4 out of the given function.

4(x^2 + 3x )

Now there is an ex on either side of the plus sign that can come out. If 4 can come out because a 4 is on either side of the plus sign, so can an ex.

4x(x + 3)

What have you found?

4 is a factor

x is a factor

x + 3 is a factor

What about 3x. Well it won't work evenly and a factor must divide evenly into the given function.
