Hi,

I've hit abit of a roadblock. I was wondering, how would I solve this (using the differntiation rules, not by first principles.) I can't see how to approach this. Could someone show working (such as expanding / factorising) in order to be able to use those rules to solve:

Differentiate with respect to x: $\displaystyle \frac{4x^2+2x}{x^2}$

Thanks!
