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

Divide each side by '2'.
-75 + 0.5x + x2 = 0

Move the constant term to the right:

Add '75' to each side of the equation.
-75 + 0.5x + 75 + x2 = 0 + 75

Reorder the terms:
-75 + 75 + 0.5x + x2 = 0 + 75

Combine like terms: -75 + 75 = 0
0 + 0.5x + x2 = 0 + 75
0.5x + x2 = 0 + 75

Combine like terms: 0 + 75 = 75
0.5x + x2 = 75

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 = 75 + 0.0625

Reorder the terms:
0.0625 + 0.5x + x2 = 75 + 0.0625

Combine like terms: 75 + 0.0625 = 75.0625
0.0625 + 0.5x + x2 = 75.0625
