Hello everyone,

I'm having trouble finding the sums of functions.

My particular problem is,

f(x)=radical(x2-4) ; g(x)=x2/x2+1

They're asking me to solve (f+g)(x).

If (f+g)(x) is the same thing as f(x)+g(x) then:

radical(x2-4)+x2/x2+1

(x-2)+?

Can x2/x2+1 be simplified so I can add the two functions easier?

I tried simplifying a bunch of things but I can't seem to get anywhere.

Any help would be appreciated. Thanks in advance!
