0.75 + -0.5x + x2 = 0.0

Move the constant term to the right:

Add '-0.75' to each side of the equation.
0.75 + -0.5x + -0.75 + x2 = 0.0 + -0.75

Reorder the terms:
0.75 + -0.75 + -0.5x + x2 = 0.0 + -0.75

Combine like terms: 0.75 + -0.75 = 0.00
0.00 + -0.5x + x2 = 0.0 + -0.75
-0.5x + x2 = 0.0 + -0.75

Combine like terms: 0.0 + -0.75 = -0.75
-0.5x + x2 = -0.75

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.
