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

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

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

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

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

Combine like terms: -6x + 4x = -2x
