Simplifying
X3 + 5x + 6 = 0
Reorder the terms:
6 + X3 + 5x = 0
Solving
6 + X3 + 5x = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + X3 + -6 + 5x = 0 + -6
Reorder the terms:
6 + -6 + X3 + 5x = 0 + -6
Combine like terms: 6 + -6 = 0
0 + X3 + 5x = 0 + -6
X3 + 5x = 0 + -6
Combine like terms: 0 + -6 = -6
X3 + 5x = -6
Add '-5x' to each side of the equation.
X3 + 5x + -5x = -6 + -5x
Combine like terms: 5x + -5x = 0
X3 + 0 = -6 + -5x
X3 = -6 + -5x
Simplifying
X3 = -6 + -5x
Reorder the terms:
6 + X3 + 5x = -6 + -5x + 6 + 5x
Reorder the terms:
6 + X3 + 5x = -6 + 6 + -5x + 5x
Combine like terms: -6 + 6 = 0
6 + X3 + 5x = 0 + -5x + 5x
6 + X3 + 5x = -5x + 5x
Combine like terms: -5x + 5x = 0
6 + X3 + 5x = 0
The solution to this equation could not be determined.
