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

Divide each side by '2.5'.
3.2 + -3.6x + x2 = 0

Move the constant term to the right:

Add '-3.2' to each side of the equation.
3.2 + -3.6x + -3.2 + x2 = 0 + -3.2

Reorder the terms:
3.2 + -3.2 + -3.6x + x2 = 0 + -3.2

Combine like terms: 3.2 + -3.2 = 0.0
0.0 + -3.6x + x2 = 0 + -3.2
-3.6x + x2 = 0 + -3.2

Combine like terms: 0 + -3.2 = -3.2
-3.6x + x2 = -3.2

The x term is -3.6x.  Take half its coefficient (-1.8).
Square it (3.24) and add it to both sides.

Add '3.24' to each side of the equation.
-3.6x + 3.24 + x2 = -3.2 + 3.24

Reorder the terms:
3.24 + -3.6x + x2 = -3.2 + 3.24

Combine like terms: -3.2 + 3.24 = 0.04
3.24 + -3.6x + x2 = 0.04

Factor a perfect square on the left side:
(x + -1.8)(x + -1.8) = 0.04

Calculate the square root of the right side: 0.2

Break this problem into two subproblems by setting 
(x + -1.8) equal to 0.2 and -0.2.

Subproblem 1

x + -1.8 = 0.2 Simplifying x + -1.8 = 0.2 Reorder the terms: -1.8 + x = 0.2 Solving -1.8 + x = 0.2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.8' to each side of the equation. -1.8 + 1.8 + x = 0.2 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + x = 0.2 + 1.8 x = 0.2 + 1.8 Combine like terms: 0.2 + 1.8 = 2 x = 2 Simplifying x = 2

Subproblem 2

x + -1.8 = -0.2 Simplifying x + -1.8 = -0.2 Reorder the terms: -1.8 + x = -0.2 Solving -1.8 + x = -0.2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.8' to each side of the equation. -1.8 + 1.8 + x = -0.2 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + x = -0.2 + 1.8 x = -0.2 + 1.8 Combine like terms: -0.2 + 1.8 = 1.6 x = 1.6 Simplifying x = 1.6

Solution

The solution to the problem is based on the solutions from the subproblems. x = {2, 1.6}
