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


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

Reorder the terms:
3y(-2 + y)(y + 3) = 0

Reorder the terms:
3y(-2 + y)(3 + y) = 0

Multiply (-2 + y) * (3 + y)
3y(-2(3 + y) + y(3 + y)) = 0
3y((3 * -2 + y * -2) + y(3 + y)) = 0
3y((-6 + -2y) + y(3 + y)) = 0
3y(-6 + -2y + (3 * y + y * y)) = 0
3y(-6 + -2y + (3y + y2)) = 0

Combine like terms: -2y + 3y = 1y
3y(-6 + 1y + y2) = 0
(-6 * 3y + 1y * 3y + y2 * 3y) = 0
(-18y + 3y2 + 3y3) = 0

Solving
-18y + 3y2 + 3y3 = 0

Solving for variable 'y'.

Factor out the Greatest Common Factor (GCF), '3y'.

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 '(-3 + -1y)' equal to zero and attempt to solve: Simplifying -3 + -1y = 0 Solving -3 + -1y = 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 + -1y = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -1y = 0 + 3 -1y = 0 + 3 Combine like terms: 0 + 3 = 3 -1y = 3 Divide each side by '-1'. y = -3 Simplifying y = -3

Subproblem 3

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, -3, 2}
