(x+11)(x-11)=

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

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

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

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

Multiply (11 + x) * (-11 + x)
(11(-11 + x) + x(-11 + x)) = 0
((-11 * 11 + x * 11) + x(-11 + x)) = 0
((-121 + 11x) + x(-11 + x)) = 0
(-121 + 11x + (-11 * x + x * x)) = 0
(-121 + 11x + (-11x + x2)) = 0

Combine like terms: 11x + -11x = 0
(-121 + 0 + x2) = 0
(-121 + x2) = 0

Solving
-121 + x2 = 0

Solving for variable 'x'.

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

Add '121' to each side of the equation.
-121 + 121 + x2 = 0 + 121

Combine like terms: -121 + 121 = 0
0 + x2 = 0 + 121
x2 = 0 + 121

Combine like terms: 0 + 121 = 121
x2 = 121

Simplifying
x2 = 121

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