Solving for variable 'b'.

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

Divide each side by '8'.
0.125 + -3b + b2 = 0

Move the constant term to the right:

Add '-0.125' to each side of the equation.
0.125 + -3b + -0.125 + b2 = 0 + -0.125

Reorder the terms:
0.125 + -0.125 + -3b + b2 = 0 + -0.125

Combine like terms: 0.125 + -0.125 = 0.000
0.000 + -3b + b2 = 0 + -0.125
-3b + b2 = 0 + -0.125

Combine like terms: 0 + -0.125 = -0.125
-3b + b2 = -0.125

The b term is -3b.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3b + 2.25 + b2 = -0.125 + 2.25

Reorder the terms:
2.25 + -3b + b2 = -0.125 + 2.25

Combine like terms: -0.125 + 2.25 = 2.125
2.25 + -3b + b2 = 2.125

Factor a perfect square on the left side:
(b + -1.5)(b + -1.5) = 2.125
