$$xdy-ydx=\left(x^2+y^2\right)dx$$
How can I solve this differential equation? which type is this equation? I don't think it is separable and I don't think it's linear too, but it might be homogenous or exact maybe!
I tried to take partial derivatives of them by splitting them into $P(x)$ and $Q(x)$ to know if it's exact or not, but I didn't get any solutions.
which type this equation is and what's the answer with steps, please!
