Break this problem into two subproblems by setting 
(x + 1) equal to 1.732050808 and -1.732050808.

Subproblem 1
x + 1 = 1.732050808

Simplifying
x + 1 = 1.732050808

Reorder the terms:
1 + x = 1.732050808

Solving
1 + x = 1.732050808

Solving for variable 'x'.

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 = 1.732050808 + -1

Combine like terms: 1 + -1 = 0
0 + x = 1.732050808 + -1
x = 1.732050808 + -1

Combine like terms: 1.732050808 + -1 = 0.732050808
x = 0.732050808

Simplifying
x = 0.732050808

Subproblem 2
x + 1 = -1.732050808

Simplifying
x + 1 = -1.732050808

Reorder the terms:
1 + x = -1.732050808

Solving
1 + x = -1.732050808

Solving for variable 'x'.

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 = -1.732050808 + -1

Combine like terms: 1 + -1 = 0
0 + x = -1.732050808 + -1
x = -1.732050808 + -1

Combine like terms: -1.732050808 + -1 = -2.732050808
x = -2.732050808

Simplifying
x = -2.732050808

Solution
The solution to the problem is based on the solutions
from the subproblems.
x = {0.732050808, -2.732050808}
Solution
x = {0.732050808, -2.732050808}
