Homework Statement



Hello everybody :) Now, I have a differential equation to solve. Its a Bernoulli's type of eq.


Homework Equations



(2x2lny-x)y' = y

The Attempt at a Solution



I tried of putting it in this way: y'/y = 1/2x2lny-x and then considerin z=1/y, but it doesnt seem to solve the problem, because the lny sort of gets in the way. Any help would be appreciated. Thanks :)

Substitute [itex]z=\ln y[/itex] into the equation. Hint: Evaluate the derivative [itex]z'[/itex] first!
