Subproblem 1
Set the factor '(-8 + u + u2)' equal to zero and attempt to solve:

Simplifying
-8 + u + u2 = 0

Solving
-8 + u + u2 = 0

Begin completing the square.

Move the constant term to the right:

Add '8' to each side of the equation.
-8 + u + 8 + u2 = 0 + 8

Reorder the terms:
-8 + 8 + u + u2 = 0 + 8

Combine like terms: -8 + 8 = 0
0 + u + u2 = 0 + 8
u + u2 = 0 + 8

Combine like terms: 0 + 8 = 8
u + u2 = 8

The u term is u.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
u + 0.25 + u2 = 8 + 0.25

Reorder the terms:
0.25 + u + u2 = 8 + 0.25

Combine like terms: 8 + 0.25 = 8.25
0.25 + u + u2 = 8.25

Factor a perfect square on the left side:
(u + 0.5)(u + 0.5) = 8.25

Calculate the square root of the right side: 2.872281323

Break this problem into two subproblems by setting 
(u + 0.5) equal to 2.872281323 and -2.872281323.


Subproblem 1
u + 0.5 = 2.872281323

Simplifying
u + 0.5 = 2.872281323

Reorder the terms:
0.5 + u = 2.872281323

Solving
0.5 + u = 2.872281323

Solving for variable 'u'.

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

Add '-0.5' to each side of the equation.
0.5 + -0.5 + u = 2.872281323 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + u = 2.872281323 + -0.5
u = 2.872281323 + -0.5

Combine like terms: 2.872281323 + -0.5 = 2.372281323
u = 2.372281323

Simplifying
u = 2.372281323


Subproblem 2
u + 0.5 = -2.872281323

Simplifying
u + 0.5 = -2.872281323

Reorder the terms:
0.5 + u = -2.872281323

Solving
0.5 + u = -2.872281323

Solving for variable 'u'.

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

Add '-0.5' to each side of the equation.
0.5 + -0.5 + u = -2.872281323 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + u = -2.872281323 + -0.5
u = -2.872281323 + -0.5

Combine like terms: -2.872281323 + -0.5 = -3.372281323
u = -3.372281323

Simplifying
u = -3.372281323
