(x-12)(x-1)=0

Solution for (x-12)(x-1)=0 equation:

Simplifying
(x + -12)(x + -1) = 0

Reorder the terms:
(-12 + x)(x + -1) = 0

Reorder the terms:
(-12 + x)(-1 + x) = 0

Multiply (-12 + x) * (-1 + x)
(-12(-1 + x) + x(-1 + x)) = 0
((-1 * -12 + x * -12) + x(-1 + x)) = 0
((12 + -12x) + x(-1 + x)) = 0
(12 + -12x + (-1 * x + x * x)) = 0
(12 + -12x + (-1x + x2)) = 0

Combine like terms: -12x + -1x = -13x
(12 + -13x + x2) = 0

Solving
12 + -13x + x2 = 0

Solving for variable 'x'.
