Solving for variable 'x'.

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

Divide each side by '8'.
0.375 + -0.75x + x2 = 0

Move the constant term to the right:

Add '-0.375' to each side of the equation.
0.375 + -0.75x + -0.375 + x2 = 0 + -0.375

Reorder the terms:
0.375 + -0.375 + -0.75x + x2 = 0 + -0.375

Combine like terms: 0.375 + -0.375 = 0.000
0.000 + -0.75x + x2 = 0 + -0.375
-0.75x + x2 = 0 + -0.375

Combine like terms: 0 + -0.375 = -0.375
-0.75x + x2 = -0.375

The x term is -0.75x.  Take half its coefficient (-0.375).
