Solution for 0=6(x+2)(x-1) equation: 


Simplifying
0 = 6(x + 2)(x + -1)

Reorder the terms:
0 = 6(2 + x)(x + -1)

Reorder the terms:
0 = 6(2 + x)(-1 + x)

Multiply (2 + x) * (-1 + x)
0 = 6(2(-1 + x) + x(-1 + x))
0 = 6((-1 * 2 + x * 2) + x(-1 + x))
0 = 6((-2 + 2x) + x(-1 + x))
0 = 6(-2 + 2x + (-1 * x + x * x))
0 = 6(-2 + 2x + (-1x + x2))

Combine like terms: 2x + -1x = 1x
0 = 6(-2 + 1x + x2)
0 = (-2 * 6 + 1x * 6 + x2 * 6)
0 = (-12 + 6x + 6x2)

Solving
0 = -12 + 6x + 6x2

Solving for variable 'x'.

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

Reorder the terms:
12 + -6x + -6x2 = -12 + 12 + 6x + -6x + 6x2 + -6x2

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

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

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

Factor out the Greatest Common Factor (GCF), '6'.
6(2 + -1x + -1x2) = 0

Factor a trinomial.
6((1 + -1x)(2 + x)) = 0

Ignore the factor 6.
