solve the differential equation:

x*y*(dy/dx) = 3x^2 + y^2

i have real problems with differential equations so if anyone could give a brief method or some reasoning id really appreciate it. Thanks

If you express it in the form

dy / dx + ay = f(x)

you can use the integrating factor method. - Jul 24th 2008, 01:59 PMwingless

Oh of course, yes. It's homogeneous. Sorry for my previous posting. It was rubbish.
