1. ## how to approach this eqation(diff)

$x^2pp''+2xp'-1=0$

its a simplified
i had a third derivative i put p=y'
and i got the equation.
i cant separate it by variables on each side.

i cant solve it a not lenear homogenic
i cant treat it as bernuly equation

??

2. What was the original equation?
