Solving for variable 'x'.

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

Divide each side by '8'.
0.875 + -0.375x + x2 = 0

Move the constant term to the right:

Add '-0.875' to each side of the equation.
0.875 + -0.375x + -0.875 + x2 = 0 + -0.875

Reorder the terms:
0.875 + -0.875 + -0.375x + x2 = 0 + -0.875

Combine like terms: 0.875 + -0.875 = 0.000
0.000 + -0.375x + x2 = 0 + -0.875
-0.375x + x2 = 0 + -0.875

Combine like terms: 0 + -0.875 = -0.875
-0.375x + x2 = -0.875

The x term is -0.375x.  Take half its coefficient (-0.1875).
Square it (0.03515625) and add it to both sides.

Add '0.03515625' to each side of the equation.
-0.375x + 0.03515625 + x2 = -0.875 + 0.03515625

Reorder the terms:
0.03515625 + -0.375x + x2 = -0.875 + 0.03515625

Combine like terms: -0.875 + 0.03515625 = -0.83984375
0.03515625 + -0.375x + x2 = -0.83984375

Factor a perfect square on the left side:
(x + -0.1875)(x + -0.1875) = -0.83984375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
