Solution for 3ydx=(3x^2-1)(dx-dy) equation:


Simplifying
3ydx = (3x2 + -1)(dx + -1dy)

Reorder the terms:
3dxy = (-1 + 3x2)(dx + -1dy)

Multiply (-1 + 3x2) * (dx + -1dy)
3dxy = (-1(dx + -1dy) + 3x2 * (dx + -1dy))
3dxy = ((dx * -1 + -1dy * -1) + 3x2 * (dx + -1dy))
3dxy = ((-1dx + 1dy) + 3x2 * (dx + -1dy))
3dxy = (-1dx + 1dy + (dx * 3x2 + -1dy * 3x2))

Reorder the terms:
3dxy = (-1dx + 1dy + (-3dx2y + 3dx3))
3dxy = (-1dx + 1dy + (-3dx2y + 3dx3))

Reorder the terms:
3dxy = (-1dx + -3dx2y + 3dx3 + 1dy)
3dxy = (-1dx + -3dx2y + 3dx3 + 1dy)

Solving
3dxy = -1dx + -3dx2y + 3dx3 + 1dy
