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

Divide each side by '8'.
0.375 + 0.5b + b2 = 0

Move the constant term to the right:

Add '-0.375' to each side of the equation.
0.375 + 0.5b + -0.375 + b2 = 0 + -0.375

Reorder the terms:
0.375 + -0.375 + 0.5b + b2 = 0 + -0.375

Combine like terms: 0.375 + -0.375 = 0.000
0.000 + 0.5b + b2 = 0 + -0.375
0.5b + b2 = 0 + -0.375

Combine like terms: 0 + -0.375 = -0.375
0.5b + b2 = -0.375

The b term is 0.5b.  Take half its coefficient (0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
0.5b + 0.0625 + b2 = -0.375 + 0.0625

Reorder the terms:
0.0625 + 0.5b + b2 = -0.375 + 0.0625

Combine like terms: -0.375 + 0.0625 = -0.3125
0.0625 + 0.5b + b2 = -0.3125

Factor a perfect square on the left side:
(b + 0.25)(b + 0.25) = -0.3125

Can't calculate square root of the right side.
