Thanks, Coomast, for help.

I'm interested in solving this 3rd order DE y'''=3*y*y' with conds y(0)=-2, y'(0)=0, y''(0)=4,5. Thanks for any ideas.. I've the right solution, but the problem is how to achieve it.

The right solutions are y^2=2*(C^3)*x + C^2 and 27*(x^2)*(y^2)=1. Hmm.. Lagrange method doesn't fit properly here

I tried this way, but it didn't give me any positive result. Moreover even Maple can't solve it exact.. it gives me huge expression..

Hello Everybody! Have any suggestions how to solve this differential equation, I haven't.. :( y(y-2x(y'))^3=(y')^2
