Now on to your question.

$f(x)=(x^2+3x-4)$
$g(x)=(x+4)$

Part (a):
$f(x)\times g(x)$

You have any thoughts on how to set about this part?

I know you use the the foil method to get the answer but the setting it up part is where im in need of help.

austinl · Answer

$f(x)\times g(x)\Rightarrow(f\times g)(x)$
 
Just multiply the two of them together. Doing so requires quite a bit of distribution. You should end up with 6 terms when done.
