Add '-0.8333333333' to each side of the equation.
0.8333333333 + 0.5x + -0.8333333333 + x2 = 0 + -0.8333333333

Reorder the terms:
0.8333333333 + -0.8333333333 + 0.5x + x2 = 0 + -0.8333333333

Combine like terms: 0.8333333333 + -0.8333333333 = 0.0000000000
0.0000000000 + 0.5x + x2 = 0 + -0.8333333333
0.5x + x2 = 0 + -0.8333333333

Combine like terms: 0 + -0.8333333333 = -0.8333333333
0.5x + x2 = -0.8333333333
