this is linear algebra & differential equation level.
i need to make it into exact and solve for the answer which is y= +_ [x^2+_ (x^4 + c)^1/2]^1/2

ex: (y^3-x^2y)y' - xy^2 = 0

In general, for a function F, 
$$ dF = \frac{\partial F}{\partial x} dx + \frac{\partial F}{\partial y} dy $$

After looking at it, I don't think you can write the above expression as a perfect differential unless you added terms to it.
