Move the constant term to the right:

Add '-1' to each side of the equation.
1 + -0.6666666667x + -1 + x2 = 0 + -1

Reorder the terms:
1 + -1 + -0.6666666667x + x2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -0.6666666667x + x2 = 0 + -1
-0.6666666667x + x2 = 0 + -1

Combine like terms: 0 + -1 = -1
-0.6666666667x + x2 = -1

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 = -1 + 0.1111111112

Reorder the terms:
0.1111111112 + -0.6666666667x + x2 = -1 + 0.1111111112
