Given the functions:
f(x)=6x
g(x)=x+9
h(x)=2x2+25x+63

Determine each of the following.

Give your answers as simplified expressions written in descending order.
Find and simplify g(x)+h(x)g(x)+h(x)=
 
Find and simplify h(x)-g(x)h(x)-g(x)=
 
Find and simplify f(x)h(x)f(x)h(x)=
 
Find and simplify h(x)g(x), hint: you will need to factor h(x)h(x)g(x)=
 
The domain restriction for g(x)f(x) is x
