Solution for y=y^2+4y equation:


Simplifying
y = y2 + 4y

Reorder the terms:
y = 4y + y2

Solving
y = 4y + y2

Solving for variable 'y'.

Combine like terms: y + -4y = -3y
-3y + -1y2 = 4y + y2 + -4y + -1y2

Reorder the terms:
-3y + -1y2 = 4y + -4y + y2 + -1y2

Combine like terms: 4y + -4y = 0
-3y + -1y2 = 0 + y2 + -1y2
-3y + -1y2 = y2 + -1y2

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

Factor out the Greatest Common Factor (GCF), '-1y'.
-1y(3 + y) = 0

Ignore the factor -1.

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 + y)' equal to zero and attempt to solve: Simplifying 3 + y = 0 Solving 3 + y = 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 + y = 0 + -3 Combine like terms: 3 + -3 = 0 0 + y = 0 + -3 y = 0 + -3 Combine like terms: 0 + -3 = -3 y = -3 Simplifying y = -3

Solution

y = {0, -3}
