Break this problem into two subproblems by setting 
(u + 1) equal to 5.744562647 and -5.744562647.

Subproblem 1
u + 1 = 5.744562647

Simplifying
u + 1 = 5.744562647

Reorder the terms:
1 + u = 5.744562647

Solving
1 + u = 5.744562647

Solving for variable 'u'.

Move all terms containing u to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + u = 5.744562647 + -1

Combine like terms: 1 + -1 = 0
0 + u = 5.744562647 + -1
u = 5.744562647 + -1

Combine like terms: 5.744562647 + -1 = 4.744562647
u = 4.744562647

Simplifying
u = 4.744562647

Subproblem 2
u + 1 = -5.744562647

Simplifying
u + 1 = -5.744562647

Reorder the terms:
1 + u = -5.744562647

Solving
1 + u = -5.744562647

Solving for variable 'u'.

Move all terms containing u to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + u = -5.744562647 + -1

Combine like terms: 1 + -1 = 0
0 + u = -5.744562647 + -1
u = -5.744562647 + -1

Combine like terms: -5.744562647 + -1 = -6.744562647
u = -6.744562647

Simplifying
u = -6.744562647

Solution
The solution to the problem is based on the solutions
from the subproblems.
u = {4.744562647, -6.744562647}
