I know there are other ways to obtain the product rule proff but my teacher got me started and I want to finish it this way and also have you guys explain WHY to do each step.(adsbygoogle = window.adsbygoogle || []).push({});

So far I have:

(f(x)g(x))' = f'(x)g(x) + f(x)g'(x)

lim (F(x+h) - F(x))/h as h->0

lim (f(x+h)g(x+h) - f(x)g(x))/h as h->0

and now I'm stuck, lol, thanks!
