Divide each side by '8'.
-0.125 + -0.5x + x2 = 0

Move the constant term to the right:

Add '0.125' to each side of the equation.
-0.125 + -0.5x + 0.125 + x2 = 0 + 0.125

Reorder the terms:
-0.125 + 0.125 + -0.5x + x2 = 0 + 0.125

Combine like terms: -0.125 + 0.125 = 0.000
0.000 + -0.5x + x2 = 0 + 0.125
-0.5x + x2 = 0 + 0.125
