Solving for variable 'x'.

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

Divide each side by '10'.
2.1 + -1.1x + x2 = 0.0

Move the constant term to the right:

Add '-2.1' to each side of the equation.
2.1 + -1.1x + -2.1 + x2 = 0.0 + -2.1

Reorder the terms:
2.1 + -2.1 + -1.1x + x2 = 0.0 + -2.1

Combine like terms: 2.1 + -2.1 = 0.0
0.0 + -1.1x + x2 = 0.0 + -2.1
-1.1x + x2 = 0.0 + -2.1

Combine like terms: 0.0 + -2.1 = -2.1
-1.1x + x2 = -2.1

The x term is -1.1x.  Take half its coefficient (-0.55).
Square it (0.3025) and add it to both sides.

Add '0.3025' to each side of the equation.
-1.1x + 0.3025 + x2 = -2.1 + 0.3025

Reorder the terms:
0.3025 + -1.1x + x2 = -2.1 + 0.3025

Combine like terms: -2.1 + 0.3025 = -1.7975
0.3025 + -1.1x + x2 = -1.7975

Factor a perfect square on the left side:
(x + -0.55)(x + -0.55) = -1.7975

Can't calculate square root of the right side.
