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

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

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

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

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

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

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

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

Solving
12 + -6x + -6x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '6'.

Subproblem 1
Set the factor '(1 + -1x)' equal to zero and attempt to solve:

Simplifying
1 + -1x = 0

Solving
1 + -1x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + -1x = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -1x = 0 + -1
-1x = 0 + -1

Combine like terms: 0 + -1 = -1
-1x = -1

Divide each side by '-1'.
x = 1

Simplifying
x = 1
Subproblem 2
Set the factor '(2 + x)' equal to zero and attempt to solve:

Simplifying
2 + x = 0

Solving
2 + x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation.
2 + -2 + x = 0 + -2

Combine like terms: 2 + -2 = 0
0 + x = 0 + -2
x = 0 + -2

Combine like terms: 0 + -2 = -2
x = -2

Simplifying
x = -2
Solution
x = {1, -2}
