Divide each side by '8'.
0.125 + -0.625x + x2 = 0

Move the constant term to the right:

Add '-0.125' to each side of the equation.
0.125 + -0.625x + -0.125 + x2 = 0 + -0.125

Reorder the terms:
0.125 + -0.125 + -0.625x + x2 = 0 + -0.125

Combine like terms: 0.125 + -0.125 = 0.000
0.000 + -0.625x + x2 = 0 + -0.125
-0.625x + x2 = 0 + -0.125
