Simplifying
4b2 = b + -2

Reorder the terms:
4b2 = -2 + b

Solving
4b2 = -2 + b

Solving for variable 'b'.

Reorder the terms:
2 + -1b + 4b2 = -2 + b + 2 + -1b

Reorder the terms:
2 + -1b + 4b2 = -2 + 2 + b + -1b

Combine like terms: -2 + 2 = 0
2 + -1b + 4b2 = 0 + b + -1b
2 + -1b + 4b2 = b + -1b

Combine like terms: b + -1b = 0
2 + -1b + 4b2 = 0

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

Divide each side by '4'.
0.5 + -0.25b + b2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -0.25b + -0.5 + b2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -0.25b + b2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -0.25b + b2 = 0 + -0.5
-0.25b + b2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-0.25b + b2 = -0.5

The b term is -0.25b.  Take half its coefficient (-0.125).
Square it (0.015625) and add it to both sides.

Add '0.015625' to each side of the equation.
-0.25b + 0.015625 + b2 = -0.5 + 0.015625

Reorder the terms:
0.015625 + -0.25b + b2 = -0.5 + 0.015625

Combine like terms: -0.5 + 0.015625 = -0.484375
0.015625 + -0.25b + b2 = -0.484375

Factor a perfect square on the left side:
(b + -0.125)(b + -0.125) = -0.484375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
