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

Divide each side by '8'.
0.625 + 0.75x + x2 = 0

Move the constant term to the right:

Add '-0.625' to each side of the equation.
0.625 + 0.75x + -0.625 + x2 = 0 + -0.625

Reorder the terms:
0.625 + -0.625 + 0.75x + x2 = 0 + -0.625

Combine like terms: 0.625 + -0.625 = 0.000
0.000 + 0.75x + x2 = 0 + -0.625
0.75x + x2 = 0 + -0.625

Combine like terms: 0 + -0.625 = -0.625
0.75x + x2 = -0.625

The x term is 0.75x.  Take half its coefficient (0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
0.75x + 0.140625 + x2 = -0.625 + 0.140625

Reorder the terms:
0.140625 + 0.75x + x2 = -0.625 + 0.140625

Combine like terms: -0.625 + 0.140625 = -0.484375
0.140625 + 0.75x + x2 = -0.484375

Factor a perfect square on the left side:
(x + 0.375)(x + 0.375) = -0.484375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
