250 + -1275 + b + -1b2 = 1275 + -1275

Combine like terms: 250 + -1275 = -1025
-1025 + b + -1b2 = 1275 + -1275

Combine like terms: 1275 + -1275 = 0
-1025 + b + -1b2 = 0

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

Divide each side by '-1'.
1025 + -1b + b2 = 0

Move the constant term to the right:

Add '-1025' to each side of the equation.
1025 + -1b + -1025 + b2 = 0 + -1025

Reorder the terms:
1025 + -1025 + -1b + b2 = 0 + -1025

Combine like terms: 1025 + -1025 = 0
0 + -1b + b2 = 0 + -1025
-1b + b2 = 0 + -1025

Combine like terms: 0 + -1025 = -1025
-1b + b2 = -1025

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 = -1025 + 0.25

Reorder the terms:
0.25 + -1b + b2 = -1025 + 0.25

Combine like terms: -1025 + 0.25 = -1024.75
0.25 + -1b + b2 = -1024.75

Factor a perfect square on the left side:
(b + 0.5)(b + 0.5) = -1024.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
