Solving for variable 'c'.

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

Divide each side by '5'.
0.2 + -2.2c + c2 = 0

Move the constant term to the right:

Add '-0.2' to each side of the equation.
0.2 + -2.2c + -0.2 + c2 = 0 + -0.2

Reorder the terms:
0.2 + -0.2 + -2.2c + c2 = 0 + -0.2

Combine like terms: 0.2 + -0.2 = 0.0
0.0 + -2.2c + c2 = 0 + -0.2
-2.2c + c2 = 0 + -0.2

Combine like terms: 0 + -0.2 = -0.2
-2.2c + c2 = -0.2

The c term is -2.2c.  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.
-2.2c + 1.21 + c2 = -0.2 + 1.21

Reorder the terms:
1.21 + -2.2c + c2 = -0.2 + 1.21

Combine like terms: -0.2 + 1.21 = 1.01
1.21 + -2.2c + c2 = 1.01

Factor a perfect square on the left side:
(c + -1.1)(c + -1.1) = 1.01

Calculate the square root of the right side: 1.004987562

Break this problem into two subproblems by setting 
(c + -1.1) equal to 1.004987562 and -1.004987562.

Subproblem 1
c + -1.1 = 1.004987562

Simplifying
c + -1.1 = 1.004987562

Reorder the terms:
-1.1 + c = 1.004987562

Solving
-1.1 + c = 1.004987562

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '1.1' to each side of the equation.
-1.1 + 1.1 + c = 1.004987562 + 1.1

Combine like terms: -1.1 + 1.1 = 0.0
0.0 + c = 1.004987562 + 1.1
c = 1.004987562 + 1.1

Combine like terms: 1.004987562 + 1.1 = 2.104987562
c = 2.104987562

Simplifying
c = 2.104987562

Subproblem 2
c + -1.1 = -1.004987562

Simplifying
c + -1.1 = -1.004987562

Reorder the terms:
-1.1 + c = -1.004987562

Solving
-1.1 + c = -1.004987562

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '1.1' to each side of the equation.
-1.1 + 1.1 + c = -1.004987562 + 1.1

Combine like terms: -1.1 + 1.1 = 0.0
0.0 + c = -1.004987562 + 1.1
c = -1.004987562 + 1.1

Combine like terms: -1.004987562 + 1.1 = 0.095012438
c = 0.095012438

Simplifying
c = 0.095012438

Solution
The solution to the problem is based on the solutions
from the subproblems.
c = {2.104987562, 0.095012438}
