Solving for variable 'b'.

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

Divide each side by '4'.
40.5 + 0.75b + b2 = 0

Move the constant term to the right:

Add '-40.5' to each side of the equation.
40.5 + 0.75b + -40.5 + b2 = 0 + -40.5

Reorder the terms:
40.5 + -40.5 + 0.75b + b2 = 0 + -40.5

Combine like terms: 40.5 + -40.5 = 0.0
0.0 + 0.75b + b2 = 0 + -40.5
0.75b + b2 = 0 + -40.5

Combine like terms: 0 + -40.5 = -40.5
0.75b + b2 = -40.5

The b term is 0.75b.  Take half its coefficient (0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
0.75b + 0.140625 + b2 = -40.5 + 0.140625

Reorder the terms:
0.140625 + 0.75b + b2 = -40.5 + 0.140625

Combine like terms: -40.5 + 0.140625 = -40.359375
0.140625 + 0.75b + b2 = -40.359375

Factor a perfect square on the left side:
(b + 0.375)(b + 0.375) = -40.359375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
