Solution for x=x^3+2x equation:


Simplifying
x = x3 + 2x

Reorder the terms:
x = 2x + x3

Solving
x = 2x + x3

Solving for variable 'x'.

Combine like terms: x + -2x = -1x
-1x + -1x3 = 2x + x3 + -2x + -1x3

Reorder the terms:
-1x + -1x3 = 2x + -2x + x3 + -1x3

Combine like terms: 2x + -2x = 0
-1x + -1x3 = 0 + x3 + -1x3
-1x + -1x3 = x3 + -1x3

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

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

Ignore the factor -1.

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 + x2)' equal to zero and attempt to solve: Simplifying 1 + x2 = 0 Solving 1 + x2 = 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 + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x2 = 0 + -1 x2 = 0 + -1 Combine like terms: 0 + -1 = -1 x2 = -1 Simplifying x2 = -1 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
