(D^2+D-2)y=0

Solution for (D^2+D-2)y=0 equation:

Simplifying
(D2 + D + -2) * y = 0

Reorder the terms:
(-2 + D + D2) * y = 0

Reorder the terms for easier multiplication:
y(-2 + D + D2) = 0
(-2 * y + D * y + D2 * y) = 0
(-2y + yD + yD2) = 0

Solving
-2y + yD + yD2 = 0

Solving for variable 'y'.

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

Factor out the Greatest Common Factor (GCF), 'y'.

Factor a trinomial.
y((-2 + -1D)(1 + -1D)) = 0

Subproblem 1
Set the factor 'y' equal to zero and attempt to solve:

Simplifying
y = 0

Solving
y = 0

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

Simplifying
y = 0
Subproblem 2
Set the factor '(-2 + -1D)' equal to zero and attempt to solve:

Simplifying
-2 + -1D = 0

Solving
-2 + -1D = 0

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

Add '2' to each side of the equation.
-2 + 2 + -1D = 0 + 2

Combine like terms: -2 + 2 = 0
0 + -1D = 0 + 2
-1D = 0 + 2

Combine like terms: 0 + 2 = 2
-1D = 2

Add 'D' to each side of the equation.
-1D + D = 2 + D

Combine like terms: -1D + D = 0
0 = 2 + D

Simplifying
0 = 2 + D

The solution to this equation could not be determined.

This subproblem is being ignored because a solution could not be determined.
Subproblem 3
Set the factor '(1 + -1D)' equal to zero and attempt to solve:

Simplifying
1 + -1D = 0

Solving
1 + -1D = 0

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

Add '-1' to each side of the equation.
1 + -1 + -1D = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -1D = 0 + -1
-1D = 0 + -1

Combine like terms: 0 + -1 = -1
-1D = -1

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

Combine like terms: -1D + D = 0
0 = -1 + D

Simplifying
0 = -1 + D
