Solution for 2y(2y+3)=6y(y-1) equation:


Simplifying
2y(2y + 3) = 6y(y + -1)

Reorder the terms:
2y(3 + 2y) = 6y(y + -1)
(3 * 2y + 2y * 2y) = 6y(y + -1)
(6y + 4y2) = 6y(y + -1)

Reorder the terms:
6y + 4y2 = 6y(-1 + y)
6y + 4y2 = (-1 * 6y + y * 6y)
6y + 4y2 = (-6y + 6y2)

Solving
6y + 4y2 = -6y + 6y2

Solving for variable 'y'.

Reorder the terms:
6y + 6y + 4y2 + -6y2 = -6y + 6y2 + 6y + -6y2

Combine like terms: 6y + 6y = 12y
12y + 4y2 + -6y2 = -6y + 6y2 + 6y + -6y2

Combine like terms: 4y2 + -6y2 = -2y2
12y + -2y2 = -6y + 6y2 + 6y + -6y2

Reorder the terms:
12y + -2y2 = -6y + 6y + 6y2 + -6y2

Combine like terms: -6y + 6y = 0
12y + -2y2 = 0 + 6y2 + -6y2
12y + -2y2 = 6y2 + -6y2

Combine like terms: 6y2 + -6y2 = 0
12y + -2y2 = 0

Factor out the Greatest Common Factor (GCF), '2y'.
2y(6 + -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 '(6 + -1y)' equal to zero and attempt to solve: Simplifying 6 + -1y = 0 Solving 6 + -1y = 0 Move all terms containing y to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + -1y = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1y = 0 + -6 -1y = 0 + -6 Combine like terms: 0 + -6 = -6 -1y = -6 Divide each side by '-1'. y = 6 Simplifying y = 6

Solution

y = {0, 6}
