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

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

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

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

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

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

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

Solving
4 + -4x + x2 = x

Solving for variable 'x'.

Solving
4 + -1x = 0

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

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

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

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

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

Simplifying
x = 4
Solution
x = {1, 4}
