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

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

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

Reorder the terms:
(-2 + x)(x + -2) = 0

Reorder the terms:
(-2 + x)(-2 + x) = 0

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

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

Solving
4 + -4x + x2 = 0
