Solution for xdy-ydx=y^3(x^2+y^2)dy equation:


Simplifying
xdy + -1ydx = y3(x2 + y2) * dy

Combine like terms: dxy + -1dxy = 0
0 = y3(x2 + y2) * dy

Reorder the terms for easier multiplication:
0 = y3 * dy(x2 + y2)

Multiply y3 * dy
0 = dy4(x2 + y2)
0 = (x2 * dy4 + y2 * dy4)
0 = (dx2y4 + dy6)

Solving
0 = dx2y4 + dy6

Solving for variable 'd'.

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

Add '-1dx2y4' to each side of the equation.
0 + -1dx2y4 = dx2y4 + -1dx2y4 + dy6
Remove the zero:
-1dx2y4 = dx2y4 + -1dx2y4 + dy6

Combine like terms: dx2y4 + -1dx2y4 = 0
-1dx2y4 = 0 + dy6
-1dx2y4 = dy6

Add '-1dy6' to each side of the equation.
-1dx2y4 + -1dy6 = dy6 + -1dy6

Combine like terms: dy6 + -1dy6 = 0
-1dx2y4 + -1dy6 = 0

Factor out the Greatest Common Factor (GCF), '-1dy4'.
-1dy4(x2 + y2) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'dy4' equal to zero and attempt to solve: Simplifying dy4 = 0 Solving dy4 = 0 Move all terms containing d to the left, all other terms to the right. Simplifying dy4 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(x2 + y2)' equal to zero and attempt to solve: Simplifying x2 + y2 = 0 Solving x2 + y2 = 0 Move all terms containing d to the left, all other terms to the right. Add '-1x2' to each side of the equation. x2 + -1x2 + y2 = 0 + -1x2 Combine like terms: x2 + -1x2 = 0 0 + y2 = 0 + -1x2 y2 = 0 + -1x2 Remove the zero: y2 = -1x2 Add '-1y2' to each side of the equation. y2 + -1y2 = -1x2 + -1y2 Combine like terms: y2 + -1y2 = 0 0 = -1x2 + -1y2 Simplifying 0 = -1x2 + -1y2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
