Divide each side by '6'.
-0.8333333333 + -0.5s + s2 = 0

Move the constant term to the right:

Add '0.8333333333' to each side of the equation.
-0.8333333333 + -0.5s + 0.8333333333 + s2 = 0 + 0.8333333333

Reorder the terms:
-0.8333333333 + 0.8333333333 + -0.5s + s2 = 0 + 0.8333333333

Combine like terms: -0.8333333333 + 0.8333333333 = 0.0000000000
0.0000000000 + -0.5s + s2 = 0 + 0.8333333333
-0.5s + s2 = 0 + 0.8333333333

Combine like terms: 0 + 0.8333333333 = 0.8333333333
-0.5s + s2 = 0.8333333333

The s term is -0.5s.  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.
-0.5s + 0.0625 + s2 = 0.8333333333 + 0.0625

Reorder the terms:
0.0625 + -0.5s + s2 = 0.8333333333 + 0.0625

Combine like terms: 0.8333333333 + 0.0625 = 0.8958333333
0.0625 + -0.5s + s2 = 0.8958333333
