Solution for xdy-ydx=4y(x^2+y^2)dx equation:


Simplifying
xdy + -1ydx = 4y(x2 + y2) * dx

Combine like terms: dxy + -1dxy = 0
0 = 4y(x2 + y2) * dx

Reorder the terms for easier multiplication:
0 = 4y * dx(x2 + y2)

Multiply y * dx
0 = 4dxy(x2 + y2)
0 = (x2 * 4dxy + y2 * 4dxy)

Reorder the terms:
0 = (4dxy3 + 4dx3y)
0 = (4dxy3 + 4dx3y)

Solving
0 = 4dxy3 + 4dx3y

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-4dxy3' to each side of the equation.
0 + -4dxy3 = 4dxy3 + -4dxy3 + 4dx3y
Remove the zero:
-4dxy3 = 4dxy3 + -4dxy3 + 4dx3y

Combine like terms: 4dxy3 + -4dxy3 = 0
-4dxy3 = 0 + 4dx3y
-4dxy3 = 4dx3y

Add '-4dx3y' to each side of the equation.
-4dxy3 + -4dx3y = 4dx3y + -4dx3y

Combine like terms: 4dx3y + -4dx3y = 0
-4dxy3 + -4dx3y = 0

Factor out the Greatest Common Factor (GCF), '-4dxy'.
-4dxy(y2 + x2) = 0

Ignore the factor -4.

Subproblem 1

Set the factor 'dxy' equal to zero and attempt to solve: Simplifying dxy = 0 Solving dxy = 0 Move all terms containing d to the left, all other terms to the right. Simplifying dxy = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2
