What's the question? Are you adding, multiplying?

cgreenwade2000 · Answer

Refresh your page, see if that helps with the reply button. If you're multiplying the two functions, you should come up with an x^2 term.

cgreenwade2000 · Answer

I would use the FOIL method to make it a little easier/neater when you try it

cgreenwade2000 · Answer

ex: I'm going to multiply 2x + 5 and -x + 3

(2x+5)(-x + 3)

F: -2x^2
O: 6x
I: -5x
L: 15

-2x^2+6x-5x+15 and then combine like terms.

-2x^2+x+15

of course you have no way of knowing what the question is 
$$f(x)g(x)\f(x)+g(x)\
f(x)-g(x)\
f(g(x))$$ how knows?
