Solving for variable 'b'.

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

Divide each side by '10'.
-3.5 + -0.3b + b2 = 0

Move the constant term to the right:

Add '3.5' to each side of the equation.
-3.5 + -0.3b + 3.5 + b2 = 0 + 3.5

Reorder the terms:
-3.5 + 3.5 + -0.3b + b2 = 0 + 3.5

Combine like terms: -3.5 + 3.5 = 0.0
0.0 + -0.3b + b2 = 0 + 3.5
-0.3b + b2 = 0 + 3.5

Combine like terms: 0 + 3.5 = 3.5
-0.3b + b2 = 3.5

The b term is -0.3b.  Take half its coefficient (-0.15).
Square it (0.0225) and add it to both sides.

Add '0.0225' to each side of the equation.
-0.3b + 0.0225 + b2 = 3.5 + 0.0225

Reorder the terms:
0.0225 + -0.3b + b2 = 3.5 + 0.0225

Combine like terms: 3.5 + 0.0225 = 3.5225
0.0225 + -0.3b + b2 = 3.5225

Factor a perfect square on the left side:
(b + -0.15)(b + -0.15) = 3.5225

Calculate the square root of the right side: 1.876832438
