Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-8 the coefficient of the squared term: 

Divide each side by '-8'.
0.375 + -2x + x2 = 0

Move the constant term to the right:

Add '-0.375' to each side of the equation.
0.375 + -2x + -0.375 + x2 = 0 + -0.375

Reorder the terms:
0.375 + -0.375 + -2x + x2 = 0 + -0.375

Combine like terms: 0.375 + -0.375 = 0.000
0.000 + -2x + x2 = 0 + -0.375
-2x + x2 = 0 + -0.375

Combine like terms: 0 + -0.375 = -0.375
-2x + x2 = -0.375

The x term is -2x.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2x + 1 + x2 = -0.375 + 1

Reorder the terms:
1 + -2x + x2 = -0.375 + 1

Combine like terms: -0.375 + 1 = 0.625
1 + -2x + x2 = 0.625

Factor a perfect square on the left side:
(x + -1)(x + -1) = 0.625

Calculate the square root of the right side: 0.790569415

Break this problem into two subproblems by setting 
(x + -1) equal to 0.790569415 and -0.790569415.

Subproblem 1
x + -1 = 0.790569415

Simplifying
x + -1 = 0.790569415

Reorder the terms:
-1 + x = 0.790569415

Solving
-1 + x = 0.790569415

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 = 0.790569415 + 1

Combine like terms: -1 + 1 = 0
0 + x = 0.790569415 + 1
x = 0.790569415 + 1

Combine like terms: 0.790569415 + 1 = 1.790569415
x = 1.790569415

Simplifying
x = 1.790569415

Subproblem 2
x + -1 = -0.790569415

Simplifying
x + -1 = -0.790569415

Reorder the terms:
-1 + x = -0.790569415

Solving
-1 + x = -0.790569415

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 = -0.790569415 + 1

Combine like terms: -1 + 1 = 0
0 + x = -0.790569415 + 1
x = -0.790569415 + 1

Combine like terms: -0.790569415 + 1 = 0.209430585
x = 0.209430585

Simplifying
x = 0.209430585

Solution
