i think, it's not f(x+h)=f(x)/h but, f(x+h)f(x)/h

ok will substitute x + h for x thats what f(x + h) is asking you to do \[\frac{(x + h)^2 2(x +h) + 4  (x^2 2x + 4)}{h}\] the next step is to expand and then collect like terms... this will leave the numerator with terms involving h which will be able to cancel with the denominator
