Solution for xdy=dx(y^2-1) equation:


Simplifying
xdy = dx(y2 + -1)

Reorder the terms:
dxy = dx(-1 + y2)
dxy = (-1 * dx + y2 * dx)
dxy = (-1dx + dxy2)

Solving
dxy = -1dx + dxy2

Solving for variable 'd'.

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

Add 'dx' to each side of the equation.
dx + dxy = -1dx + dx + dxy2

Combine like terms: -1dx + dx = 0
dx + dxy = 0 + dxy2
dx + dxy = dxy2

Add '-1dxy2' to each side of the equation.
dx + dxy + -1dxy2 = dxy2 + -1dxy2

Combine like terms: dxy2 + -1dxy2 = 0
dx + dxy + -1dxy2 = 0

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

Subproblem 1

Set the factor 'dx' equal to zero and attempt to solve: Simplifying dx = 0 Solving dx = 0 Move all terms containing d to the left, all other terms to the right. Simplifying dx = 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 '(1 + y + -1y2)' equal to zero and attempt to solve: Simplifying 1 + y + -1y2 = 0 Solving 1 + y + -1y2 = 0 Move all terms containing d to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + y + -1 + -1y2 = 0 + -1 Reorder the terms: 1 + -1 + y + -1y2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + y + -1y2 = 0 + -1 y + -1y2 = 0 + -1 Combine like terms: 0 + -1 = -1 y + -1y2 = -1 Add '-1y' to each side of the equation. y + -1y + -1y2 = -1 + -1y Combine like terms: y + -1y = 0 0 + -1y2 = -1 + -1y -1y2 = -1 + -1y Add 'y2' to each side of the equation. -1y2 + y2 = -1 + -1y + y2 Combine like terms: -1y2 + y2 = 0 0 = -1 + -1y + y2 Simplifying 0 = -1 + -1y + y2 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.
