(3+h)(3+h)=

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

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

Multiply (3 + h) * (3 + h)
(3(3 + h) + h(3 + h)) = 0
((3 * 3 + h * 3) + h(3 + h)) = 0
((9 + 3h) + h(3 + h)) = 0
(9 + 3h + (3 * h + h * h)) = 0
(9 + 3h + (3h + h2)) = 0

Combine like terms: 3h + 3h = 6h
(9 + 6h + h2) = 0

Solving
9 + 6h + h2 = 0

Solving for variable 'h'.

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

Subproblem 1
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
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 = {-3, -3}
