(h+11)(h-11)=

Solution for (h+11)(h-11)= equation:

Simplifying
(h + 11)(h + -11) = 0

Reorder the terms:
(11 + h)(h + -11) = 0

Reorder the terms:
(11 + h)(-11 + h) = 0

Multiply (11 + h) * (-11 + h)
(11(-11 + h) + h(-11 + h)) = 0
((-11 * 11 + h * 11) + h(-11 + h)) = 0
((-121 + 11h) + h(-11 + h)) = 0
(-121 + 11h + (-11 * h + h * h)) = 0
(-121 + 11h + (-11h + h2)) = 0

Combine like terms: 11h + -11h = 0
(-121 + 0 + h2) = 0
(-121 + h2) = 0

Solving
-121 + h2 = 0

Solving for variable 'h'.

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

Add '121' to each side of the equation.
-121 + 121 + h2 = 0 + 121

Combine like terms: -121 + 121 = 0
0 + h2 = 0 + 121
h2 = 0 + 121

Combine like terms: 0 + 121 = 121
h2 = 121

Simplifying
h2 = 121

Take the square root of each side:
h = {-11, 11}
