Solving for variable 'x'.

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

Divide each side by '2.5'.
0.92 + -2.2x + x2 = 0

Move the constant term to the right:

Add '-0.92' to each side of the equation.
0.92 + -2.2x + -0.92 + x2 = 0 + -0.92

Reorder the terms:
0.92 + -0.92 + -2.2x + x2 = 0 + -0.92

Combine like terms: 0.92 + -0.92 = 0.00
0.00 + -2.2x + x2 = 0 + -0.92
-2.2x + x2 = 0 + -0.92

Combine like terms: 0 + -0.92 = -0.92
-2.2x + x2 = -0.92

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 = -0.92 + 1.21

Reorder the terms:
1.21 + -2.2x + x2 = -0.92 + 1.21

Combine like terms: -0.92 + 1.21 = 0.29
1.21 + -2.2x + x2 = 0.29

Factor a perfect square on the left side:
(x + -1.1)(x + -1.1) = 0.29

Calculate the square root of the right side: 0.538516481

Break this problem into two subproblems by setting 
(x + -1.1) equal to 0.538516481 and -0.538516481.

Subproblem 1

x + -1.1 = 0.538516481 Simplifying x + -1.1 = 0.538516481 Reorder the terms: -1.1 + x = 0.538516481 Solving -1.1 + x = 0.538516481 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.1' to each side of the equation. -1.1 + 1.1 + x = 0.538516481 + 1.1 Combine like terms: -1.1 + 1.1 = 0.0 0.0 + x = 0.538516481 + 1.1 x = 0.538516481 + 1.1 Combine like terms: 0.538516481 + 1.1 = 1.638516481 x = 1.638516481 Simplifying x = 1.638516481

Subproblem 2

x + -1.1 = -0.538516481 Simplifying x + -1.1 = -0.538516481 Reorder the terms: -1.1 + x = -0.538516481 Solving -1.1 + x = -0.538516481 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.1' to each side of the equation. -1.1 + 1.1 + x = -0.538516481 + 1.1 Combine like terms: -1.1 + 1.1 = 0.0 0.0 + x = -0.538516481 + 1.1 x = -0.538516481 + 1.1 Combine like terms: -0.538516481 + 1.1 = 0.561483519 x = 0.561483519 Simplifying x = 0.561483519
