(x-1)(3x+6)=0

Solution for (x-1)(3x+6)=0 equation:

Simplifying
(x + -1)(3x + 6) = 0

Reorder the terms:
(-1 + x)(3x + 6) = 0

Reorder the terms:
(-1 + x)(6 + 3x) = 0

Multiply (-1 + x) * (6 + 3x)
(-1(6 + 3x) + x(6 + 3x)) = 0
((6 * -1 + 3x * -1) + x(6 + 3x)) = 0
((-6 + -3x) + x(6 + 3x)) = 0
(-6 + -3x + (6 * x + 3x * x)) = 0
(-6 + -3x + (6x + 3x2)) = 0

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

Solving
-6 + 3x + 3x2 = 0
