Best ResponseYou've already chosen the best response.0basically by canceling out the h and 5x^2

Best ResponseYou've already chosen the best response.1did you mean f(x)=x^2 ? cos i don't see how you can start working that out if you haven't defined f(x) in the first place :/

Best ResponseYou've already chosen the best response.2you have to substitute (x+h) for x in f(x+h), you're not going to end up with 0

Best ResponseYou've already chosen the best response.1ok so you'll do what Dockworker said and you'll end up with this. \[\huge \frac{5(x+h)^25x^2}{h} \]\[\huge \text{simplify that and I believe that'd be it :) } \]
