Solution for (x-1)(x+12)=6x equation:


Simplifying
(x + -1)(x + 12) = 6x

Reorder the terms:
(-1 + x)(x + 12) = 6x

Reorder the terms:
(-1 + x)(12 + x) = 6x

Multiply (-1 + x) * (12 + x)
(-1(12 + x) + x(12 + x)) = 6x
((12 * -1 + x * -1) + x(12 + x)) = 6x
((-12 + -1x) + x(12 + x)) = 6x
(-12 + -1x + (12 * x + x * x)) = 6x
(-12 + -1x + (12x + x2)) = 6x

Combine like terms: -1x + 12x = 11x
(-12 + 11x + x2) = 6x

Solving
-12 + 11x + x2 = 6x

Solving for variable 'x'.
