b-b^2=2.25

Solution for b-b^2=2.25 equation:

Simplifying
b + -1b2 = 2.25

Solving
b + -1b2 = 2.25

Solving for variable 'b'.

Reorder the terms:
-2.25 + b + -1b2 = 2.25 + -2.25

Combine like terms: 2.25 + -2.25 = 0.00
-2.25 + b + -1b2 = 0.00

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

Divide each side by '-1'.
2.25 + -1b + b2 = 0.00

Move the constant term to the right:

Add '-2.25' to each side of the equation.
2.25 + -1b + -2.25 + b2 = 0.00 + -2.25

Reorder the terms:
2.25 + -2.25 + -1b + b2 = 0.00 + -2.25

Combine like terms: 2.25 + -2.25 = 0.00
0.00 + -1b + b2 = 0.00 + -2.25
-1b + b2 = 0.00 + -2.25

Combine like terms: 0.00 + -2.25 = -2.25
-1b + b2 = -2.25

The b term is b.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1b + 0.25 + b2 = -2.25 + 0.25

Reorder the terms:
0.25 + -1b + b2 = -2.25 + 0.25

Combine like terms: -2.25 + 0.25 = -2
0.25 + -1b + b2 = -2

Factor a perfect square on the left side:
(b + 0.5)(b + 0.5) = -2

Can't calculate square root of the right side.
