(3x+6)(x-2)=

Solution for (3x+6)(x-2)= equation:

Simplifying
(3x + 6)(x + -2) = 0

Reorder the terms:
(6 + 3x)(x + -2) = 0

Reorder the terms:
(6 + 3x)(-2 + x) = 0

Multiply (6 + 3x) * (-2 + x)
(6(-2 + x) + 3x * (-2 + x)) = 0
((-2 * 6 + x * 6) + 3x * (-2 + x)) = 0
((-12 + 6x) + 3x * (-2 + x)) = 0
(-12 + 6x + (-2 * 3x + x * 3x)) = 0
(-12 + 6x + (-6x + 3x2)) = 0

Combine like terms: 6x + -6x = 0
(-12 + 0 + 3x2) = 0
(-12 + 3x2) = 0
