(x-1.2)(x+1.2)=0

Solution for (x-1.2)(x+1.2)=0 equation:

Simplifying
(x + -1.2)(x + 1.2) = 0

Reorder the terms:
(-1.2 + x)(x + 1.2) = 0

Reorder the terms:
(-1.2 + x)(1.2 + x) = 0

Multiply (-1.2 + x) * (1.2 + x)
(-1.2(1.2 + x) + x(1.2 + x)) = 0
((1.2 * -1.2 + x * -1.2) + x(1.2 + x)) = 0
((-1.44 + -1.2x) + x(1.2 + x)) = 0
(-1.44 + -1.2x + (1.2 * x + x * x)) = 0
(-1.44 + -1.2x + (1.2x + x2)) = 0

Combine like terms: -1.2x + 1.2x = 0.0
(-1.44 + 0.0 + x2) = 0
(-1.44 + x2) = 0

Solving
-1.44 + x2 = 0

Solving for variable 'x'.

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

Add '1.44' to each side of the equation.
-1.44 + 1.44 + x2 = 0 + 1.44

Combine like terms: -1.44 + 1.44 = 0.00
0.00 + x2 = 0 + 1.44
x2 = 0 + 1.44

Combine like terms: 0 + 1.44 = 1.44
x2 = 1.44

Simplifying
x2 = 1.44

Take the square root of each side:
x = {-1.2, 1.2}
