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

Divide each side by '-3'.
133.3333333 + -6t + t2 = 0

Move the constant term to the right:

Add '-133.3333333' to each side of the equation.
133.3333333 + -6t + -133.3333333 + t2 = 0 + -133.3333333

Reorder the terms:
133.3333333 + -133.3333333 + -6t + t2 = 0 + -133.3333333

Combine like terms: 133.3333333 + -133.3333333 = 0.0000000
0.0000000 + -6t + t2 = 0 + -133.3333333
-6t + t2 = 0 + -133.3333333

Combine like terms: 0 + -133.3333333 = -133.3333333
-6t + t2 = -133.3333333

The t term is -6t.  Take half its coefficient (-3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
-6t + 9 + t2 = -133.3333333 + 9

Reorder the terms:
9 + -6t + t2 = -133.3333333 + 9

Combine like terms: -133.3333333 + 9 = -124.3333333
9 + -6t + t2 = -124.3333333

Factor a perfect square on the left side:
(t + -3)(t + -3) = -124.3333333

Can't calculate square root of the right side.

The solution to this equation could not be determined.
