Solving
-14 + 1x + -1x2 = 0

Solving for variable 'x'.

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

Divide each side by '-1'.
14 + -1x + x2 = 0

Move the constant term to the right:

Add '-14' to each side of the equation.
14 + -1x + -14 + x2 = 0 + -14

Reorder the terms:
14 + -14 + -1x + x2 = 0 + -14

Combine like terms: 14 + -14 = 0
0 + -1x + x2 = 0 + -14
-1x + x2 = 0 + -14

Combine like terms: 0 + -14 = -14
-1x + x2 = -14

The x term is -1x.  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.
-1x + 0.25 + x2 = -14 + 0.25
