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

Divide each side by '-3'.
16.66666667 + -1x + x2 = 0

Move the constant term to the right:

Add '-16.66666667' to each side of the equation.
16.66666667 + -1x + -16.66666667 + x2 = 0 + -16.66666667

Reorder the terms:
16.66666667 + -16.66666667 + -1x + x2 = 0 + -16.66666667

Combine like terms: 16.66666667 + -16.66666667 = 0.00000000
0.00000000 + -1x + x2 = 0 + -16.66666667
-1x + x2 = 0 + -16.66666667

Combine like terms: 0 + -16.66666667 = -16.66666667
-1x + x2 = -16.66666667

The x term is -1x.  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.
-1x + 0.25 + x2 = -16.66666667 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -16.66666667 + 0.25

Combine like terms: -16.66666667 + 0.25 = -16.41666667
0.25 + -1x + x2 = -16.41666667

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = -16.41666667

Can't calculate square root of the right side.

The solution to this equation could not be determined.
