find the general solution of
i know this is a first order non linear differential eqn
but how to solve this equation
i divided by xy tried to make this exact and then find the integrating factor but i am unable to do so
help
I suppose that it is a textbook exercice. So, it cannot be as difficult as the solving of the above ODE.
This draw to think that there is a typo in the equation.
For example, the corrected ODE might be as shown below. Then the integrating factor would be 1/(xy)^4

It isn't exact, I can't find an integrating factor, and it's not homogeneous. I'm starting to side with "JJ". You may have transcribed it correctly, but I'm guessing the book itself might have a typo.
i divided it by xy then separated dx and dy terms to get
ydx+xdy+2xy^3dx-x^2ydy=0
then
d(xy)+i can make this part exact by calculating the integrating factor in terms of y and then solving it

Take into consideration the answers already given and conclude by yourself.
