Solution for (12x-6)(x+2)=0 equation:

Simplifying
(12x + -6)(x + 2) = 0

Reorder the terms:
(-6 + 12x)(x + 2) = 0

Reorder the terms:
(-6 + 12x)(2 + x) = 0

Multiply (-6 + 12x) * (2 + x)
(-6(2 + x) + 12x * (2 + x)) = 0
((2 * -6 + x * -6) + 12x * (2 + x)) = 0
((-12 + -6x) + 12x * (2 + x)) = 0
(-12 + -6x + (2 * 12x + x * 12x)) = 0
(-12 + -6x + (24x + 12x2)) = 0

Combine like terms: -6x + 24x = 18x
