Solution for 2y=2y(y-1) equation:


Simplifying
2y = 2y(y + -1)

Reorder the terms:
2y = 2y(-1 + y)
2y = (-1 * 2y + y * 2y)
2y = (-2y + 2y2)

Solving
2y = -2y + 2y2

Solving for variable 'y'.

Combine like terms: 2y + 2y = 4y
4y + -2y2 = -2y + 2y2 + 2y + -2y2

Reorder the terms:
4y + -2y2 = -2y + 2y + 2y2 + -2y2

Combine like terms: -2y + 2y = 0
4y + -2y2 = 0 + 2y2 + -2y2
4y + -2y2 = 2y2 + -2y2

Combine like terms: 2y2 + -2y2 = 0
4y + -2y2 = 0

Factor out the Greatest Common Factor (GCF), '2y'.
2y(2 + -1y) = 0

Ignore the factor 2.

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 + -1y)' equal to zero and attempt to solve: Simplifying 2 + -1y = 0 Solving 2 + -1y = 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 + -1y = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1y = 0 + -2 -1y = 0 + -2 Combine like terms: 0 + -2 = -2 -1y = -2 Divide each side by '-1'. y = 2 Simplifying y = 2

Solution

y = {0, 2}
