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

Divide each side by '2'.
-12 + -0.5x + x2 = 0

Move the constant term to the right:

Add '12' to each side of the equation.
-12 + -0.5x + 12 + x2 = 0 + 12

Reorder the terms:
-12 + 12 + -0.5x + x2 = 0 + 12

Combine like terms: -12 + 12 = 0
0 + -0.5x + x2 = 0 + 12
-0.5x + x2 = 0 + 12

Combine like terms: 0 + 12 = 12
-0.5x + x2 = 12

The x term is -0.5x.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5x + 0.0625 + x2 = 12 + 0.0625

Reorder the terms:
0.0625 + -0.5x + x2 = 12 + 0.0625

Combine like terms: 12 + 0.0625 = 12.0625
0.0625 + -0.5x + x2 = 12.0625
