Ok, the site went down while I was answering this.

"We can combine the functions based on the question.

(f-g)(x)

3x + 2 - 2x - 2

We can combine like terms. Do you know how to do that?"

anonymous · Answer

i know what it is ill get some else help if your gonna be smart about it

anonymous · Answer

no i do not know how to do that

♪chibiterasu · Answer

Ok, well. If you had 4x and -5x you could combine them. They are like terms because they both have the variable 'x'. Since -5x is negative, we have to subtract

4x - 5x = -1x or just -x.

Now if we had 2x and 6x^2, we can't combine them. They both have the variable 'x' but 6x^2 has an exponent, so they are not the same and we cannot combine.

♪chibiterasu · Answer

Our like terms in this problem are:

3x and -2x
2 and -2

anonymous · Answer

so my answer is x

♪chibiterasu · Answer

Yeah.

♪chibiterasu · Answer

3x - 2x = x
2 - 2 = 0

x :3
