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

Divide each side by '3'.
800 + -0.6666666667x + x2 = 0

Move the constant term to the right:

Add '-800' to each side of the equation.
800 + -0.6666666667x + -800 + x2 = 0 + -800

Reorder the terms:
800 + -800 + -0.6666666667x + x2 = 0 + -800

Combine like terms: 800 + -800 = 0
0 + -0.6666666667x + x2 = 0 + -800
-0.6666666667x + x2 = 0 + -800

Combine like terms: 0 + -800 = -800
-0.6666666667x + x2 = -800

The x term is -0.6666666667x.  Take half its coefficient (-0.3333333334).
Square it (0.1111111112) and add it to both sides.

Add '0.1111111112' to each side of the equation.
-0.6666666667x + 0.1111111112 + x2 = -800 + 0.1111111112

Reorder the terms:
0.1111111112 + -0.6666666667x + x2 = -800 + 0.1111111112

Combine like terms: -800 + 0.1111111112 = -799.8888888888
0.1111111112 + -0.6666666667x + x2 = -799.8888888888

Factor a perfect square on the left side:
(x + -0.3333333334)(x + -0.3333333334) = -799.8888888888

Can't calculate square root of the right side.
