# Calculator Output

```Simplifying
(x + 2)(x + -2) = x2 + x

Reorder the terms:
(2 + x)(x + -2) = x2 + x

Reorder the terms:
(2 + x)(-2 + x) = x2 + x

Multiply (2 + x) * (-2 + x)
(2(-2 + x) + x(-2 + x)) = x2 + x
((-2 * 2 + x * 2) + x(-2 + x)) = x2 + x
((-4 + 2x) + x(-2 + x)) = x2 + x
(-4 + 2x + (-2 * x + x * x)) = x2 + x
(-4 + 2x + (-2x + x2)) = x2 + x

Combine like terms: 2x + -2x = 0
(-4 + 0 + x2) = x2 + x
(-4 + x2) = x2 + x

Reorder the terms:
-4 + x2 = x + x2

Add '-1x2' to each side of the equation.
-4 + x2 + -1x2 = x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-4 + 0 = x + x2 + -1x2
-4 = x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-4 = x + 0
-4 = x

Solving
-4 = x

Solving for variable 'x'.

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

Add '-1x' to each side of the equation.
-4 + -1x = x + -1x

Combine like terms: x + -1x = 0
-4 + -1x = 0

Add '4' to each side of the equation.
-4 + 4 + -1x = 0 + 4

Combine like terms: -4 + 4 = 0
0 + -1x = 0 + 4
-1x = 0 + 4

Combine like terms: 0 + 4 = 4
-1x = 4

Divide each side by '-1'.
x = -4

Simplifying
x = -4```
