You can put this solution on YOUR website!
f(x) = 1/x
g(x) = 2/x^2

(f+g)(x) = f(x) + g(x) = 2/x + 2/x^2

multiply 2/x by x/x to get 2x/x^2

now you have common denominators and your equation becomes:

(f+g)(x) = f(x) + g(x) = 2x/x^2 + 2/x^2 = (2x + 2)/x^2

I assumed this is what you are looking for.

If not, let me know and we'll work from there.
