Solving for variable 'x'.

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

Divide each side by '8'.
0.25 + 0.375x + x2 = 0

Move the constant term to the right:

Add '-0.25' to each side of the equation.
0.25 + 0.375x + -0.25 + x2 = 0 + -0.25

Reorder the terms:
0.25 + -0.25 + 0.375x + x2 = 0 + -0.25

Combine like terms: 0.25 + -0.25 = 0.00
0.00 + 0.375x + x2 = 0 + -0.25
0.375x + x2 = 0 + -0.25

Combine like terms: 0 + -0.25 = -0.25
0.375x + x2 = -0.25

The x term is 0.375x.  Take half its coefficient (0.1875).
