Simplifying
0 = b2 + -3b + 4

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

Solving
0 = 4 + -3b + b2

Solving for variable 'b'.

Combine like terms: 0 + -4 = -4
-4 + 3b + -1b2 = 4 + -3b + b2 + -4 + 3b + -1b2

Reorder the terms:
-4 + 3b + -1b2 = 4 + -4 + -3b + 3b + b2 + -1b2

Combine like terms: 4 + -4 = 0
-4 + 3b + -1b2 = 0 + -3b + 3b + b2 + -1b2
-4 + 3b + -1b2 = -3b + 3b + b2 + -1b2

Combine like terms: -3b + 3b = 0
-4 + 3b + -1b2 = 0 + b2 + -1b2
-4 + 3b + -1b2 = b2 + -1b2

Combine like terms: b2 + -1b2 = 0
-4 + 3b + -1b2 = 0

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
4 + -3b + b2 = 0

Move the constant term to the right:

Add '-4' to each side of the equation.
4 + -3b + -4 + b2 = 0 + -4

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

Combine like terms: 4 + -4 = 0
0 + -3b + b2 = 0 + -4
-3b + b2 = 0 + -4

Combine like terms: 0 + -4 = -4
-3b + b2 = -4

The b term is -3b.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3b + 2.25 + b2 = -4 + 2.25

Reorder the terms:
2.25 + -3b + b2 = -4 + 2.25

Combine like terms: -4 + 2.25 = -1.75
2.25 + -3b + b2 = -1.75

Factor a perfect square on the left side:
(b + -1.5)(b + -1.5) = -1.75

Can't calculate square root of the right side.
