1. The problem statement, all variables and given/known data

Use the method for Homogeneous Equations to slove

(xy + y^2) dx - x^2 dy = 0

2. Relevant equations

3. The attempt at a solution

I attempted to get dx/dy on one side and substitute but could not get farther than this

dx/dy = x^2/(xy + y^2)

Try $y=ux,\ dy = udx + xdu$ to get a separable equation.
