(x+6)(2x-4)=0

Solution for (x+6)(2x-4)=0 equation:

Simplifying
(x + 6)(2x + -4) = 0

Reorder the terms:
(6 + x)(2x + -4) = 0

Reorder the terms:
(6 + x)(-4 + 2x) = 0

Multiply (6 + x) * (-4 + 2x)
(6(-4 + 2x) + x(-4 + 2x)) = 0
((-4 * 6 + 2x * 6) + x(-4 + 2x)) = 0
((-24 + 12x) + x(-4 + 2x)) = 0
(-24 + 12x + (-4 * x + 2x * x)) = 0
(-24 + 12x + (-4x + 2x2)) = 0

Combine like terms: 12x + -4x = 8x
(-24 + 8x + 2x2) = 0

Solving
-24 + 8x + 2x2 = 0
