Find the derivative of y=x^2 / e^2x using the Quotient Rule, and simplify.
I really need help! please! :)

http://en.wikipedia.org/wiki/Quotient_rule
y'= (2x*e^2x2e^2x*x^2)/e^4x
= (2x)(1x)/e^2x
check my work, I did it in my head. 
thank u so much! I checked it cause i used ur wikipedia link and understood it better. my teacher uses her own formula or something instead of d(x) or whatever. thank u soo much!! :)
