x(adsbygoogle = window.adsbygoogle || []).push({}); ^{2}+ y + y^{2}dx - x dy = 0

Integrating factor, I(x,y) = -1 / (x^{2}+ y^{2})

How to find the integrating factor ?

Why I cannot use below method to solve the ode ?

(1/N)(M_{y}- N_{x}) = g(x) , I(x,y)=exp( ∫ g(x) dx) OR

(1/M)(M_{y}- N_{x}) = h(y) , I(x,y)=exp( -∫ h(y) dy)
