Solution for n^3+2n=-2n^3-n equation:


Simplifying
n3 + 2n = -2n3 + -1n

Reorder the terms:
2n + n3 = -2n3 + -1n

Reorder the terms:
2n + n3 = -1n + -2n3

Solving
2n + n3 = -1n + -2n3

Solving for variable 'n'.

Reorder the terms:
2n + n + n3 + 2n3 = -1n + -2n3 + n + 2n3

Combine like terms: 2n + n = 3n
3n + n3 + 2n3 = -1n + -2n3 + n + 2n3

Combine like terms: n3 + 2n3 = 3n3
3n + 3n3 = -1n + -2n3 + n + 2n3

Reorder the terms:
3n + 3n3 = -1n + n + -2n3 + 2n3

Combine like terms: -1n + n = 0
3n + 3n3 = 0 + -2n3 + 2n3
3n + 3n3 = -2n3 + 2n3

Combine like terms: -2n3 + 2n3 = 0
3n + 3n3 = 0

Factor out the Greatest Common Factor (GCF), '3n'.
3n(1 + n2) = 0

Ignore the factor 3.

Subproblem 1

Set the factor 'n' equal to zero and attempt to solve: Simplifying n = 0 Solving n = 0 Move all terms containing n to the left, all other terms to the right. Simplifying n = 0

Subproblem 2

Set the factor '(1 + n2)' equal to zero and attempt to solve: Simplifying 1 + n2 = 0 Solving 1 + n2 = 0 Move all terms containing n to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + n2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + n2 = 0 + -1 n2 = 0 + -1 Combine like terms: 0 + -1 = -1 n2 = -1 Simplifying n2 = -1 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Solution

n = {0}
