math problem

I need some help solving the differential equation

dy/dx - 3x²y = x²

Oh god.
I'm glad I'm out of school. o_o

I was just asking what the solution was.

I got as far as Dx(e^(-x³y)) = x²e^(-x³).

Oh, nevermind. Now I remember. You just integrate both sides. Fearless, you were pretty close. The answer is y = -1/3 + Ce^(x³). Thanks.

See loook..
