find the derivative of lnx / x^2 ?

OpenStudy (nubeer):

(vu'-uv')/v^2 u=lnx , v = x^2

OpenStudy (anonymous):

I get the quotient rule but dont know what to do with the 2x(lnx) on the top? Does it end up 2lnx^2?

OpenStudy (nubeer):

no it doesnt... well i dont think so.

OpenStudy (nubeer):

2x(lnx) just leave it like this.. it's still a correct answer.
