Subproblem 1
Set the factor '(5 + -8x + x2)' equal to zero and attempt to solve:

Simplifying
5 + -8x + x2 = 0

Solving
5 + -8x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-5' to each side of the equation.
5 + -8x + -5 + x2 = 0 + -5

Reorder the terms:
5 + -5 + -8x + x2 = 0 + -5

Combine like terms: 5 + -5 = 0
0 + -8x + x2 = 0 + -5
-8x + x2 = 0 + -5

Combine like terms: 0 + -5 = -5
-8x + x2 = -5

The x term is -8x.  Take half its coefficient (-4).
Square it (16) and add it to both sides.

Add '16' to each side of the equation.
-8x + 16 + x2 = -5 + 16

Reorder the terms:
16 + -8x + x2 = -5 + 16

Combine like terms: -5 + 16 = 11
16 + -8x + x2 = 11

Factor a perfect square on the left side:
(x + -4)(x + -4) = 11

Break this problem into two subproblems by setting 
(x + -4) equal to 3.31662479 and -3.31662479.

Subproblem 1
x + -4 = 3.31662479

Simplifying
x + -4 = 3.31662479

Reorder the terms:
-4 + x = 3.31662479

Solving
-4 + x = 3.31662479

Solving for variable 'x'.

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

Add '4' to each side of the equation.
-4 + 4 + x = 3.31662479 + 4

Combine like terms: -4 + 4 = 0
0 + x = 3.31662479 + 4
x = 3.31662479 + 4

Combine like terms: 3.31662479 + 4 = 7.31662479
x = 7.31662479

Simplifying
x = 7.31662479

Subproblem 2
x + -4 = -3.31662479

Simplifying
x + -4 = -3.31662479

Reorder the terms:
-4 + x = -3.31662479

Solving
-4 + x = -3.31662479

Solving for variable 'x'.

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

Add '4' to each side of the equation.
-4 + 4 + x = -3.31662479 + 4

Combine like terms: -4 + 4 = 0
0 + x = -3.31662479 + 4
x = -3.31662479 + 4

Combine like terms: -3.31662479 + 4 = 0.68337521
x = 0.68337521

Simplifying
