find the derivative of 3x^4-5x+3/x^4+1 i know that the derivative of the numeratoor would be 12x^3-5 but i'm not sure if its right since it has a denominator i Know i need to do something to it but not sure if to simplify.

You will have to use the quotient rule. If you don't know what that is .... you'll have some major catching up to do.

ok, i know what it is had forgotten we use that but its in my notes thanks!!!!
