Solution for (x-1)(x-2)=2 equation:


Simplifying
(x + -1)(x + -2) = 2

Reorder the terms:
(-1 + x)(x + -2) = 2

Reorder the terms:
(-1 + x)(-2 + x) = 2

Multiply (-1 + x) * (-2 + x)
(-1(-2 + x) + x(-2 + x)) = 2
((-2 * -1 + x * -1) + x(-2 + x)) = 2
((2 + -1x) + x(-2 + x)) = 2
(2 + -1x + (-2 * x + x * x)) = 2
(2 + -1x + (-2x + x2)) = 2

Combine like terms: -1x + -2x = -3x
(2 + -3x + x2) = 2

Add '-2' to each side of the equation.
2 + -3x + -2 + x2 = 2 + -2
