Move the constant term to the right:

Add '-1.333333333' to each side of the equation.
1.333333333 + -0.5r + -1.333333333 + r2 = 0 + -1.333333333

Reorder the terms:
1.333333333 + -1.333333333 + -0.5r + r2 = 0 + -1.333333333

Combine like terms: 1.333333333 + -1.333333333 = 0.000000000
0.000000000 + -0.5r + r2 = 0 + -1.333333333
-0.5r + r2 = 0 + -1.333333333

Combine like terms: 0 + -1.333333333 = -1.333333333
-0.5r + r2 = -1.333333333

The r term is -0.5r.  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.
-0.5r + 0.0625 + r2 = -1.333333333 + 0.0625
