Divide each side by '12'.
0.4166666667 + -1r + r2 = 0

Move the constant term to the right:

Add '-0.4166666667' to each side of the equation.
0.4166666667 + -1r + -0.4166666667 + r2 = 0 + -0.4166666667

Reorder the terms:
0.4166666667 + -0.4166666667 + -1r + r2 = 0 + -0.4166666667

Combine like terms: 0.4166666667 + -0.4166666667 = 0.0000000000
0.0000000000 + -1r + r2 = 0 + -0.4166666667
-1r + r2 = 0 + -0.4166666667

Combine like terms: 0 + -0.4166666667 = -0.4166666667
-1r + r2 = -0.4166666667

The r term is -1r.  Take half its coefficient (-0.5).

Add '0.25' to each side of the equation.
-1r + 0.25 + r2 = -0.4166666667 + 0.25

Reorder the terms:
0.25 + -1r + r2 = -0.4166666667 + 0.25

Combine like terms: -0.4166666667 + 0.25 = -0.1666666667
0.25 + -1r + r2 = -0.1666666667

Factor a perfect square on the left side:
(r + -0.5)(r + -0.5) = -0.1666666667

Can't calculate square root of the right side.
