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

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

Simplifying
(x + 1)(x + -1) * x = 0

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

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

Reorder the terms for easier multiplication:
x(1 + x)(-1 + x) = 0

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

Combine like terms: 1x + -1x = 0
x(-1 + 0 + x2) = 0
x(-1 + x2) = 0
(-1 * x + x2 * x) = 0
(-1x + x3) = 0

Solving
-1x + x3 = 0

Subproblem 1
Set the factor 'x' equal to zero and attempt to solve:

Simplifying
x = 0

Solving
x = 0

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

Simplifying
x = 0
Subproblem 2
Set the factor '(1 + x)' equal to zero and attempt to solve:

Simplifying
1 + x = 0

Solving
1 + x = 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 + x = 0 + -1

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

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

Simplifying
x = -1
Subproblem 3
Set the factor '(-1 + x)' equal to zero and attempt to solve:

Simplifying
-1 + x = 0

Solving
-1 + x = 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 + x = 0 + 1

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

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

Simplifying
x = 1
Solution
x = {0, -1, 1}
