=h^2+4h

Solution for =h^2+4h equation:

Simplifying
0 = h2 + 4h

Reorder the terms:
0 = 4h + h2

Solving
0 = 4h + h2

Solving for variable 'h'.
Remove the zero:
-4h + -1h2 = 4h + h2 + -4h + -1h2

Reorder the terms:
-4h + -1h2 = 4h + -4h + h2 + -1h2

Combine like terms: 4h + -4h = 0
-4h + -1h2 = 0 + h2 + -1h2
-4h + -1h2 = h2 + -1h2

Combine like terms: h2 + -1h2 = 0
-4h + -1h2 = 0

Factor out the Greatest Common Factor (GCF), '-1h'.
-1h(4 + h) = 0

Ignore the factor -1.
Subproblem 1
Set the factor 'h' equal to zero and attempt to solve:

Simplifying
h = 0

Solving
h = 0

Move all terms containing h to the left, all other terms to the right.

Simplifying
h = 0
Subproblem 2
Set the factor '(4 + h)' equal to zero and attempt to solve:

Simplifying
4 + h = 0

Solving
4 + h = 0

Move all terms containing h to the left, all other terms to the right.

Add '-4' to each side of the equation.
4 + -4 + h = 0 + -4

Combine like terms: 4 + -4 = 0
0 + h = 0 + -4
h = 0 + -4

Combine like terms: 0 + -4 = -4
h = -4

Simplifying
h = -4
Solution
h = {0, -4}
