Begin completing the square.  Divide all terms by
3 the coefficient of the squared term: 

Divide each side by '3'.
1.333333333 + -1r + r2 = 0

Move the constant term to the right:

Add '-1.333333333' to each side of the equation.
1.333333333 + -1r + -1.333333333 + r2 = 0 + -1.333333333

Reorder the terms:
1.333333333 + -1.333333333 + -1r + r2 = 0 + -1.333333333

Combine like terms: 1.333333333 + -1.333333333 = 0.000000000
0.000000000 + -1r + r2 = 0 + -1.333333333
-1r + r2 = 0 + -1.333333333

Combine like terms: 0 + -1.333333333 = -1.333333333
-1r + r2 = -1.333333333

The r term is -1r.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1r + 0.25 + r2 = -1.333333333 + 0.25

Reorder the terms:
0.25 + -1r + r2 = -1.333333333 + 0.25

Combine like terms: -1.333333333 + 0.25 = -1.083333333
0.25 + -1r + r2 = -1.083333333

Factor a perfect square on the left side:
(r + -0.5)(r + -0.5) = -1.083333333

Can't calculate square root of the right side.

The solution to this equation could not be determined.
