(h+3)(h+4)=

Solution for (h+3)(h+4)= equation:

Simplifying
(h + 3)(h + 4) = 0

Reorder the terms:
(3 + h)(h + 4) = 0

Reorder the terms:
(3 + h)(4 + h) = 0

Multiply (3 + h) * (4 + h)
(3(4 + h) + h(4 + h)) = 0
((4 * 3 + h * 3) + h(4 + h)) = 0
((12 + 3h) + h(4 + h)) = 0
(12 + 3h + (4 * h + h * h)) = 0
(12 + 3h + (4h + h2)) = 0

Combine like terms: 3h + 4h = 7h
(12 + 7h + h2) = 0

Solving
12 + 7h + h2 = 0

Solving for variable 'h'.

Factor a trinomial.
(4 + h)(3 + h) = 0

Subproblem 1
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
Subproblem 2
Set the factor '(3 + h)' equal to zero and attempt to solve:

Simplifying
3 + h = 0

Solving
3 + h = 0

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

Add '-3' to each side of the equation.
3 + -3 + h = 0 + -3

Combine like terms: 3 + -3 = 0
0 + h = 0 + -3
h = 0 + -3

Combine like terms: 0 + -3 = -3
h = -3

Simplifying
h = -3
Solution
h = {-4, -3}
