Simplifying
(10b2) + -1(3b + -4) = 0

Reorder the terms:
(10b2) + -1(-4 + 3b) = 0
(10b2) + (-4 * -1 + 3b * -1) = 0
(10b2) + (4 + -3b) = 0

Reorder the terms:
4 + -3b + (10b2) = 0

Solving
4 + -3b + (10b2) = 0

Solving for variable 'b'.

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

Divide each side by '10'.
0.4 + -0.3b + b2 = 0

Move the constant term to the right:

Add '-0.4' to each side of the equation.
0.4 + -0.3b + -0.4 + b2 = 0 + -0.4

Reorder the terms:
0.4 + -0.4 + -0.3b + b2 = 0 + -0.4

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + -0.3b + b2 = 0 + -0.4
-0.3b + b2 = 0 + -0.4

Combine like terms: 0 + -0.4 = -0.4
-0.3b + b2 = -0.4

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 = -0.4 + 0.0225

Reorder the terms:
0.0225 + -0.3b + b2 = -0.4 + 0.0225

Combine like terms: -0.4 + 0.0225 = -0.3775
0.0225 + -0.3b + b2 = -0.3775

Factor a perfect square on the left side:
((b) + -0.15)((b) + -0.15) = -0.3775

Can't calculate square root of the right side.

The solution to this equation could not be determined.
