So I am trying to figure out what substitution to use for the following ODE substitution:
x^2*y' + 2xy = 5y^3; I initially moved the 2xy to the right but to no avail because when I tried to divide through by x^2 (to clear the left), I struggle to get the y/x format on the right. If the solution is obvious, I apologize, but we get zip examples in class and apparently I'm not good enough to figure this out on my own.

Try dividing by x2 and then http://en.wikipedia.org/wiki/Bernoulli_differential_equation" [Broken] :wink:.
