Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
13.5 + -0.5x + x2 = 0

Move the constant term to the right:

Add '-13.5' to each side of the equation.
13.5 + -0.5x + -13.5 + x2 = 0 + -13.5

Reorder the terms:
13.5 + -13.5 + -0.5x + x2 = 0 + -13.5

Combine like terms: 13.5 + -13.5 = 0.0
0.0 + -0.5x + x2 = 0 + -13.5
-0.5x + x2 = 0 + -13.5
