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

Divide each side by '-8'.
0.1875 + 0.125x + x2 = 0

Move the constant term to the right:

Add '-0.1875' to each side of the equation.
0.1875 + 0.125x + -0.1875 + x2 = 0 + -0.1875

Reorder the terms:
0.1875 + -0.1875 + 0.125x + x2 = 0 + -0.1875

Combine like terms: 0.1875 + -0.1875 = 0.0000
0.0000 + 0.125x + x2 = 0 + -0.1875
0.125x + x2 = 0 + -0.1875

Combine like terms: 0 + -0.1875 = -0.1875
0.125x + x2 = -0.1875

The x term is 0.125x.  Take half its coefficient (0.0625).
Square it (0.00390625) and add it to both sides.

Add '0.00390625' to each side of the equation.
0.125x + 0.00390625 + x2 = -0.1875 + 0.00390625

Reorder the terms:
0.00390625 + 0.125x + x2 = -0.1875 + 0.00390625

Combine like terms: -0.1875 + 0.00390625 = -0.18359375
0.00390625 + 0.125x + x2 = -0.18359375

Factor a perfect square on the left side:
(x + 0.0625)(x + 0.0625) = -0.18359375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
