# Differential equation

## Homework Statement

y=(xy-y^2)/x^2

## The Attempt at a Solution

y = y/x -(y/x)^2

{y/x=z , y=zx , y=z+xz}

-z^2=x*dz/dx

-z^2dx = xdz

whats next ?

Next is to move the -z^2 and x factors around so they are with, respectively, dz and dx. Then integrate.

To integrate that, you need your z's on one side and your x's on the other. Dividing through by x*z^2 should do the trick.
