Solution for x=x^3-3x equation:


Simplifying
x = x3 + -3x

Reorder the terms:
x = -3x + x3

Solving
x = -3x + x3

Solving for variable 'x'.

Combine like terms: x + 3x = 4x
4x + -1x3 = -3x + x3 + 3x + -1x3

Reorder the terms:
4x + -1x3 = -3x + 3x + x3 + -1x3

Combine like terms: -3x + 3x = 0
4x + -1x3 = 0 + x3 + -1x3
4x + -1x3 = x3 + -1x3

Combine like terms: x3 + -1x3 = 0
4x + -1x3 = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(4 + -1x2) = 0

Factor a difference between two squares.
x((2 + x)(2 + -1x)) = 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 '(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

Subproblem 3

Set the factor '(2 + -1x)' equal to zero and attempt to solve: Simplifying 2 + -1x = 0 Solving 2 + -1x = 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 + -1x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x = 0 + -2 -1x = 0 + -2 Combine like terms: 0 + -2 = -2 -1x = -2 Divide each side by '-1'. x = 2 Simplifying x = 2

Solution

x = {0, -2, 2}
