Divide each side by '4'.
-15.75 + 0.5x + x2 = 0

Move the constant term to the right:

Add '15.75' to each side of the equation.
-15.75 + 0.5x + 15.75 + x2 = 0 + 15.75

Reorder the terms:
-15.75 + 15.75 + 0.5x + x2 = 0 + 15.75

Combine like terms: -15.75 + 15.75 = 0.00
0.00 + 0.5x + x2 = 0 + 15.75
0.5x + x2 = 0 + 15.75

Combine like terms: 0 + 15.75 = 15.75
0.5x + x2 = 15.75

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 = 15.75 + 0.0625

Reorder the terms:
0.0625 + 0.5x + x2 = 15.75 + 0.0625

Combine like terms: 15.75 + 0.0625 = 15.8125
0.0625 + 0.5x + x2 = 15.8125
