Solving for variable 'x'.

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

Divide each side by '9'.
0.8888888889 + x + x2 = 0

Move the constant term to the right:

Add '-0.8888888889' to each side of the equation.
0.8888888889 + x + -0.8888888889 + x2 = 0 + -0.8888888889

Reorder the terms:
0.8888888889 + -0.8888888889 + x + x2 = 0 + -0.8888888889

Combine like terms: 0.8888888889 + -0.8888888889 = 0.0000000000
0.0000000000 + x + x2 = 0 + -0.8888888889
x + x2 = 0 + -0.8888888889

Combine like terms: 0 + -0.8888888889 = -0.8888888889
x + x2 = -0.8888888889

The x term is x.  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.
+ 0.25 + x2 = -0.8888888889 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + x2 = -0.8888888889 + 0.25

1.25 + x2 = -0.6388888889

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -0.6388888889

Can't calculate square root of the right side.
