4x(x-1)(x+1)=0

Solution for 4x(x-1)(x+1)=0 equation:

Simplifying
4x(x + -1)(x + 1) = 0

Reorder the terms:
4x(-1 + x)(x + 1) = 0

Reorder the terms:
4x(-1 + x)(1 + x) = 0

Multiply (-1 + x) * (1 + x)
4x(-1(1 + x) + x(1 + x)) = 0
4x((1 * -1 + x * -1) + x(1 + x)) = 0
4x((-1 + -1x) + x(1 + x)) = 0
4x(-1 + -1x + (1 * x + x * x)) = 0
4x(-1 + -1x + (1x + x2)) = 0

Combine like terms: -1x + 1x = 0
4x(-1 + 0 + x2) = 0
4x(-1 + x2) = 0
(-1 * 4x + x2 * 4x) = 0
(-4x + 4x3) = 0

Solving
-4x + 4x3 = 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
