(h+1)(h-1)=

Solution for (h+1)(h-1)= equation:

Simplifying
(h + 1)(h + -1) = 0

Reorder the terms:
(1 + h)(h + -1) = 0

Reorder the terms:
(1 + h)(-1 + h) = 0

Multiply (1 + h) * (-1 + h)
(1(-1 + h) + h(-1 + h)) = 0
((-1 * 1 + h * 1) + h(-1 + h)) = 0
((-1 + 1h) + h(-1 + h)) = 0
(-1 + 1h + (-1 * h + h * h)) = 0
(-1 + 1h + (-1h + h2)) = 0

Combine like terms: 1h + -1h = 0
(-1 + 0 + h2) = 0
(-1 + h2) = 0

Solving
-1 + h2 = 0

Solving for variable 'h'.

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

Add '1' to each side of the equation.
-1 + 1 + h2 = 0 + 1

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

Combine like terms: 0 + 1 = 1
h2 = 1

Simplifying
h2 = 1

Take the square root of each side:
h = {-1, 1}
