y * dx(-2 + x + -1y) + x(y + -1x + 4) * dy = 0

Multiply y * dx
dxy(-2 + x + -1y) + x(y + -1x + 4) * dy = 0
(-2 * dxy + x * dxy + -1y * dxy) + x(y + -1x + 4) * dy = 0

Reorder the terms:
(-2dxy + -1dxy2 + dx2y) + x(y + -1x + 4) * dy = 0
(-2dxy + -1dxy2 + dx2y) + x(y + -1x + 4) * dy = 0

Reorder the terms:
-2dxy + -1dxy2 + dx2y + x(4 + -1x + y) * dy = 0

Reorder the terms for easier multiplication:
-2dxy + -1dxy2 + dx2y + x * dy(4 + -1x + y) = 0

Multiply x * dy
-2dxy + -1dxy2 + dx2y + dxy(4 + -1x + y) = 0
-2dxy + -1dxy2 + dx2y + (4 * dxy + -1x * dxy + y * dxy) = 0

Reorder the terms:
-2dxy + -1dxy2 + dx2y + (4dxy + dxy2 + -1dx2y) = 0
-2dxy + -1dxy2 + dx2y + (4dxy + dxy2 + -1dx2y) = 0

Reorder the terms:
-2dxy + 4dxy + -1dxy2 + dxy2 + dx2y + -1dx2y = 0

Combine like terms: -2dxy + 4dxy = 2dxy
2dxy + -1dxy2 + dxy2 + dx2y + -1dx2y = 0

Combine like terms: -1dxy2 + dxy2 = 0
2dxy + 0 + dx2y + -1dx2y = 0
2dxy + dx2y + -1dx2y = 0
