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

Divide each side by '-1'.
139 + -23x + x2 = 0

Move the constant term to the right:

Add '-139' to each side of the equation.
139 + -23x + -139 + x2 = 0 + -139

Reorder the terms:
139 + -139 + -23x + x2 = 0 + -139

Combine like terms: 139 + -139 = 0
0 + -23x + x2 = 0 + -139
-23x + x2 = 0 + -139

Combine like terms: 0 + -139 = -139
-23x + x2 = -139

The x term is -23x.  Take half its coefficient (-11.5).
Square it (132.25) and add it to both sides.

Add '132.25' to each side of the equation.
-23x + 132.25 + x2 = -139 + 132.25

Reorder the terms:
132.25 + -23x + x2 = -139 + 132.25

Combine like terms: -139 + 132.25 = -6.75
132.25 + -23x + x2 = -6.75

Factor a perfect square on the left side:
(x + -11.5)(x + -11.5) = -6.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
