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

Divide each side by '8'.
-0.125 + -0.5x + x2 = 0

Move the constant term to the right:

Add '0.125' to each side of the equation.
-0.125 + -0.5x + 0.125 + x2 = 0 + 0.125

Reorder the terms:
-0.125 + 0.125 + -0.5x + x2 = 0 + 0.125

Combine like terms: -0.125 + 0.125 = 0.000
0.000 + -0.5x + x2 = 0 + 0.125
-0.5x + x2 = 0 + 0.125

Combine like terms: 0 + 0.125 = 0.125
-0.5x + x2 = 0.125

The x term is -0.5x.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5x + 0.0625 + x2 = 0.125 + 0.0625

Reorder the terms:
0.0625 + -0.5x + x2 = 0.125 + 0.0625

Combine like terms: 0.125 + 0.0625 = 0.1875
0.0625 + -0.5x + x2 = 0.1875
