## Homework Statement

f(x)=(2x-4)/(x+2)

g(x) = 4x2-16

find and simplyify:

1/[g(1/x)]

f(x)-g(x)

## Homework Equations

## The Attempt at a Solution

For 1/[g(1/x)]:

I got (-16x^2+4)/(x^2), but I can't figure out how to simplify this down further, this assignment had other problems and they all simplified down to a whole number so I assume this one would too.

For f(x)-g(x)

Plugged in variables, found common denominator, and ended with this mess:

[(4x^3)+(8x^2)-14x+36]/(x+2)

I am sure that can get simplified further, and tried and was really geting no where, any help on these two? Am I doing something wrong or is this the right answer ? Thanks
