Question

(1 point) Use the "mixed partials" check to see if the following differential equation is exact.
If it is exact find a function F(x,y) whose differential, dF(x,y)$dF(x,y)$ is the left hand side of the differential equation. That is, level curves F(x,y)=C$F(x,y)=C$ are solutions to the differential equation:

(3xy2−3y)dx+(3x2y−3x)dy=0$$(3x{y}^2-3y)dx+(3x^{2}y-3x)dy=0$$

First:
My(x,y)=$M_y(x,y)=$  , and Nx(x,y)=$N_x(x,y)=$  .

If the equation is not exact, enter not exact, otherwise enter in F(x,y)$F(x,y)$ here 

Note: In order to get credit for this problem all answers must be correct.
