y-y^2=y^2-3

Solution for y-y^2=y^2-3 equation:

Simplifying
y + -1y2 = y2 + -3

Reorder the terms:
y + -1y2 = -3 + y2

Solving
y + -1y2 = -3 + y2

Solving for variable 'y'.

Reorder the terms:
3 + y + -1y2 + -1y2 = -3 + y2 + 3 + -1y2

Combine like terms: -1y2 + -1y2 = -2y2
3 + y + -2y2 = -3 + y2 + 3 + -1y2

Reorder the terms:
3 + y + -2y2 = -3 + 3 + y2 + -1y2

Combine like terms: -3 + 3 = 0
3 + y + -2y2 = 0 + y2 + -1y2
3 + y + -2y2 = y2 + -1y2

Combine like terms: y2 + -1y2 = 0
3 + y + -2y2 = 0

(3 + -2y)(1 + y) = 0

Subproblem 1
Set the factor '(3 + -2y)' equal to zero and attempt to solve:

Simplifying
3 + -2y = 0

Solving
3 + -2y = 0

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

Add '-3' to each side of the equation.
3 + -3 + -2y = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -2y = 0 + -3
-2y = 0 + -3

Combine like terms: 0 + -3 = -3
-2y = -3

Divide each side by '-2'.
y = 1.5

Simplifying
y = 1.5
Subproblem 2
Set the factor '(1 + y)' equal to zero and attempt to solve:

Simplifying
1 + y = 0

Solving
1 + y = 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 + y = 0 + -1

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

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

Simplifying
y = -1
Solution
y = {1.5, -1}
