$$({\mathrm{x}}^2+{3\mathrm{y}}^2)\mathrm{dx}+(2\mathrm{xy}-\mathrm{x})\mathrm{dy}=0$$$$\mathrm{M}={\mathrm{x}}^2+{3\mathrm{y}}^2\to \frac{\partial \mathrm{M}}{\partial \mathrm{y}}=6\mathrm{y}$$$$\mathrm{N}=2\mathrm{xy}-\mathrm{x}\to \frac{\partial \mathrm{N}}{\partial \mathrm{x}}=2\mathrm{y}-1$$$$\frac{\partial \mathrm{M}}{\partial \mathrm{y}}\ne \frac{\partial \mathrm{N}}{\partial \mathrm{x}}\Leftarrow \mathrm{non}\mathrm{exact}$$
