0.3333333333 + 0.3333333333t + t2 = 0

Move the constant term to the right:

Add '-0.3333333333' to each side of the equation.
0.3333333333 + 0.3333333333t + -0.3333333333 + t2 = 0 + -0.3333333333

Reorder the terms:
0.3333333333 + -0.3333333333 + 0.3333333333t + t2 = 0 + -0.3333333333

Combine like terms: 0.3333333333 + -0.3333333333 = 0.0000000000
0.0000000000 + 0.3333333333t + t2 = 0 + -0.3333333333
0.3333333333t + t2 = 0 + -0.3333333333

Combine like terms: 0 + -0.3333333333 = -0.3333333333
0.3333333333t + t2 = -0.3333333333

The t term is t.  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.
0.3333333333t + 0.25 + t2 = -0.3333333333 + 0.25

Reorder the terms:
0.25 + 0.3333333333t + t2 = -0.3333333333 + 0.25

Combine like terms: -0.3333333333 + 0.25 = -0.0833333333
0.25 + 0.3333333333t + t2 = -0.0833333333

Factor a perfect square on the left side:
(t + 0.5)(t + 0.5) = -0.0833333333

Can't calculate square root of the right side.
