Divide each side by '3'.
3.333333333 + -9k + k2 = 0

Move the constant term to the right:

Add '-3.333333333' to each side of the equation.
3.333333333 + -9k + -3.333333333 + k2 = 0 + -3.333333333

Reorder the terms:
3.333333333 + -3.333333333 + -9k + k2 = 0 + -3.333333333

Combine like terms: 3.333333333 + -3.333333333 = 0.000000000
0.000000000 + -9k + k2 = 0 + -3.333333333
-9k + k2 = 0 + -3.333333333

Combine like terms: 0 + -3.333333333 = -3.333333333
-9k + k2 = -3.333333333

The k term is -9k.  Take half its coefficient (-4.5).
Square it (20.25) and add it to both sides.

Add '20.25' to each side of the equation.
-9k + 20.25 + k2 = -3.333333333 + 20.25
