evaluating functions
For some reason I can't get these 3 problems correct:
g(x) = x^2(x5)
g(3/2)
g(c)
g(t+2)
Any help would be greatly appreciated.
I contribute as much as I can and I don't seem to get any help. Maybe these are too hard of problems?

I will do one, and check you on the others.
g(t+2)=(t+2)^2 *(t+25)
= (t^2+2t+4)(t3)
= (t^3+2t^2 + 4t 3t^26t12)
then combine like terms. 
Can you tell me if the correct answer for this is
t^3 1t^2 2t 12 
correct

it's telling me that this answer is wrong.
for
g(c) i got c^35c
and for
g(3/2) i got 13.something and 8
but it keeps telling me i'm wrong
(it means my online class where i am working through these. however, i am not just asking you for answers, i have been sitting here on a friday night trying really hard to learn this and not getting this section...) 
isnt g(c)=c^35c^2 ?
g(3/2)=((3 / 2)^2) * ((3 / 2)  5)
= 7.87500 
can you tell me why it's 5c^2 and not 5c?

f*x)=x^25x^2
