(x+4)(3x-6)=0

Solution for (x+4)(3x-6)=0 equation:

Simplifying
(x + 4)(3x + -6) = 0

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

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

Multiply (4 + x) * (-6 + 3x)
(4(-6 + 3x) + x(-6 + 3x)) = 0
((-6 * 4 + 3x * 4) + x(-6 + 3x)) = 0
((-24 + 12x) + x(-6 + 3x)) = 0
(-24 + 12x + (-6 * x + 3x * x)) = 0
(-24 + 12x + (-6x + 3x2)) = 0

Combine like terms: 12x + -6x = 6x
(-24 + 6x + 3x2) = 0

Solving
-24 + 6x + 3x2 = 0
