I've got f(x)=x^2-(7x^2)/2-9x+3(adsbygoogle = window.adsbygoogle || []).push({});

I need to find the first derivative of it but I get as far as 2x- but I'm stumped as to what to do with (7x^2)/2 Would I use the quotiant rule? Or should I somehow bring the 2 up to the top and if so how do I do that?
