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

Divide each side by '2'.
-500 + -1.5x + x2 = 0

Move the constant term to the right:

Add '500' to each side of the equation.
-500 + -1.5x + 500 + x2 = 0 + 500

Reorder the terms:
-500 + 500 + -1.5x + x2 = 0 + 500

Combine like terms: -500 + 500 = 0
0 + -1.5x + x2 = 0 + 500
-1.5x + x2 = 0 + 500

Combine like terms: 0 + 500 = 500
-1.5x + x2 = 500

The x term is -1.5x.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5x + 0.5625 + x2 = 500 + 0.5625

Reorder the terms:
0.5625 + -1.5x + x2 = 500 + 0.5625

Combine like terms: 500 + 0.5625 = 500.5625
0.5625 + -1.5x + x2 = 500.5625
