Solving for variable 'x'.

Combine like terms: 0 + 2.3 = 2.3
2.3 + -1.1x + 0.5x2 = -2.3 + 1.1x + -0.5x2 + 2.3 + -1.1x + 0.5x2

Reorder the terms:
2.3 + -1.1x + 0.5x2 = -2.3 + 2.3 + 1.1x + -1.1x + -0.5x2 + 0.5x2

Combine like terms: -2.3 + 2.3 = 0.0
2.3 + -1.1x + 0.5x2 = 0.0 + 1.1x + -1.1x + -0.5x2 + 0.5x2
2.3 + -1.1x + 0.5x2 = 1.1x + -1.1x + -0.5x2 + 0.5x2

Combine like terms: 1.1x + -1.1x = 0.0
2.3 + -1.1x + 0.5x2 = 0.0 + -0.5x2 + 0.5x2
2.3 + -1.1x + 0.5x2 = -0.5x2 + 0.5x2

Combine like terms: -0.5x2 + 0.5x2 = 0.0
2.3 + -1.1x + 0.5x2 = 0.0

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

Divide each side by '0.5'.
4.6 + -2.2x + x2 = 0

Move the constant term to the right:

Add '-4.6' to each side of the equation.
4.6 + -2.2x + -4.6 + x2 = 0 + -4.6

Reorder the terms:
4.6 + -4.6 + -2.2x + x2 = 0 + -4.6

Combine like terms: 4.6 + -4.6 = 0.0
0.0 + -2.2x + x2 = 0 + -4.6
-2.2x + x2 = 0 + -4.6

Combine like terms: 0 + -4.6 = -4.6
-2.2x + x2 = -4.6

The x term is -2.2x.  Take half its coefficient (-1.1).
Square it (1.21) and add it to both sides.

Add '1.21' to each side of the equation.
-2.2x + 1.21 + x2 = -4.6 + 1.21

Reorder the terms:
1.21 + -2.2x + x2 = -4.6 + 1.21

Combine like terms: -4.6 + 1.21 = -3.39
1.21 + -2.2x + x2 = -3.39

Factor a perfect square on the left side:
(x + -1.1)(x + -1.1) = -3.39

Can't calculate square root of the right side.

The solution to this equation could not be determined.
