Move the constant term to the right:

Add '-0.3333333333' to each side of the equation.
0.3333333333 + -1u + -0.3333333333 + u2 = 0 + -0.3333333333

Reorder the terms:
0.3333333333 + -0.3333333333 + -1u + u2 = 0 + -0.3333333333

Combine like terms: 0.3333333333 + -0.3333333333 = 0.0000000000
0.0000000000 + -1u + u2 = 0 + -0.3333333333
-1u + u2 = 0 + -0.3333333333

Combine like terms: 0 + -0.3333333333 = -0.3333333333
-1u + u2 = -0.3333333333

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

-1u + 0.25 + u2 = -0.3333333333 + 0.25

Reorder the terms:
0.25 + -1u + u2 = -0.3333333333 + 0.25

Combine like terms: -0.3333333333 + 0.25 = -0.0833333333
0.25 + -1u + u2 = -0.0833333333

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

Can't calculate square root of the right side.

The solution to this equation could not be determined.
