Solution for 5y(y+2)-y(y-3)= equation:


Simplifying
5y(y + 2) + -1y(y + -3) = 0

Reorder the terms:
5y(2 + y) + -1y(y + -3) = 0
(2 * 5y + y * 5y) + -1y(y + -3) = 0
(10y + 5y2) + -1y(y + -3) = 0

Reorder the terms:
10y + 5y2 + -1y(-3 + y) = 0
10y + 5y2 + (-3 * -1y + y * -1y) = 0
10y + 5y2 + (3y + -1y2) = 0

Reorder the terms:
10y + 3y + 5y2 + -1y2 = 0

Combine like terms: 10y + 3y = 13y
13y + 5y2 + -1y2 = 0

Combine like terms: 5y2 + -1y2 = 4y2
13y + 4y2 = 0

Solving
13y + 4y2 = 0

Solving for variable 'y'.

Factor out the Greatest Common Factor (GCF), 'y'.
y(13 + 4y) = 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 '(13 + 4y)' equal to zero and attempt to solve: Simplifying 13 + 4y = 0 Solving 13 + 4y = 0 Move all terms containing y to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + 4y = 0 + -13 Combine like terms: 13 + -13 = 0 0 + 4y = 0 + -13 4y = 0 + -13 Combine like terms: 0 + -13 = -13 4y = -13 Divide each side by '4'. y = -3.25 Simplifying y = -3.25

Solution

y = {0, -3.25}
