(x-0.2)(x+0.2)=

Solution for (x-0.2)(x+0.2)= equation:

Simplifying
(x + -0.2)(x + 0.2) = 0

Reorder the terms:
(-0.2 + x)(x + 0.2) = 0

Reorder the terms:
(-0.2 + x)(0.2 + x) = 0

Multiply (-0.2 + x) * (0.2 + x)
(-0.2(0.2 + x) + x(0.2 + x)) = 0
((0.2 * -0.2 + x * -0.2) + x(0.2 + x)) = 0
((-0.04 + -0.2x) + x(0.2 + x)) = 0
(-0.04 + -0.2x + (0.2 * x + x * x)) = 0
(-0.04 + -0.2x + (0.2x + x2)) = 0

Combine like terms: -0.2x + 0.2x = 0.0
(-0.04 + 0.0 + x2) = 0
(-0.04 + x2) = 0

Solving
-0.04 + x2 = 0

Solving for variable 'x'.

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

Add '0.04' to each side of the equation.
-0.04 + 0.04 + x2 = 0 + 0.04

Combine like terms: -0.04 + 0.04 = 0.00
0.00 + x2 = 0 + 0.04
x2 = 0 + 0.04

Combine like terms: 0 + 0.04 = 0.04
x2 = 0.04

Simplifying
x2 = 0.04

Take the square root of each side:
x = {-0.2, 0.2}
