(2-x)(2+x)=0

Solution for (2-x)(2+x)=0 equation:

Simplifying
(2 + -1x)(2 + x) = 0

Multiply (2 + -1x) * (2 + x)
(2(2 + x) + -1x * (2 + x)) = 0
((2 * 2 + x * 2) + -1x * (2 + x)) = 0
((4 + 2x) + -1x * (2 + x)) = 0
(4 + 2x + (2 * -1x + x * -1x)) = 0
(4 + 2x + (-2x + -1x2)) = 0

Combine like terms: 2x + -2x = 0
(4 + 0 + -1x2) = 0
(4 + -1x2) = 0

Solving
4 + -1x2 = 0

Solving for variable 'x'.

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

Add '-4' to each side of the equation.
4 + -4 + -1x2 = 0 + -4

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

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

Divide each side by '-1'.
x2 = 4

Simplifying
x2 = 4

Take the square root of each side:
x = {-2, 2}
