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


Simplifying
(x * x) = (x + -2)(x + 2)

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

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

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

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

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

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

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

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