0.4285714286 + -0.4285714286b + b2 = 0

Move the constant term to the right:

Add '-0.4285714286' to each side of the equation.
0.4285714286 + -0.4285714286b + -0.4285714286 + b2 = 0 + -0.4285714286

Reorder the terms:
0.4285714286 + -0.4285714286 + -0.4285714286b + b2 = 0 + -0.4285714286

Combine like terms: 0.4285714286 + -0.4285714286 = 0.0000000000
0.0000000000 + -0.4285714286b + b2 = 0 + -0.4285714286
-0.4285714286b + b2 = 0 + -0.4285714286

Combine like terms: 0 + -0.4285714286 = -0.4285714286
-0.4285714286b + b2 = -0.4285714286

The b term is -0.4285714286b.  Take half its coefficient (-0.2142857143).
Square it (0.04591836735) and add it to both sides.

Add '0.04591836735' to each side of the equation.
-0.4285714286b + 0.04591836735 + b2 = -0.4285714286 + 0.04591836735

Reorder the terms:
0.04591836735 + -0.4285714286b + b2 = -0.4285714286 + 0.04591836735

Combine like terms: -0.4285714286 + 0.04591836735 = -0.38265306125
0.04591836735 + -0.4285714286b + b2 = -0.38265306125

Factor a perfect square on the left side:
(b + -0.2142857143)(b + -0.2142857143) = -0.38265306125

Can't calculate square root of the right side.
