Solving for variable 'x'.

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

Divide each side by '8'.
1.125 + 0.25x + x2 = 0

Move the constant term to the right:

Add '-1.125' to each side of the equation.
1.125 + 0.25x + -1.125 + x2 = 0 + -1.125

Reorder the terms:
1.125 + -1.125 + 0.25x + x2 = 0 + -1.125

Combine like terms: 1.125 + -1.125 = 0.000
0.000 + 0.25x + x2 = 0 + -1.125
0.25x + x2 = 0 + -1.125

Combine like terms: 0 + -1.125 = -1.125
0.25x + x2 = -1.125

The x term is 0.25x.  Take half its coefficient (0.125).
Square it (0.015625) and add it to both sides.

Add '0.015625' to each side of the equation.
0.25x + 0.015625 + x2 = -1.125 + 0.015625

Reorder the terms:
0.015625 + 0.25x + x2 = -1.125 + 0.015625

Combine like terms: -1.125 + 0.015625 = -1.109375
0.015625 + 0.25x + x2 = -1.109375
