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

Divide each side by '-5'.
-2.2 + 0.2x + x2 = 0

Move the constant term to the right:

Add '2.2' to each side of the equation.
-2.2 + 0.2x + 2.2 + x2 = 0 + 2.2

Reorder the terms:
-2.2 + 2.2 + 0.2x + x2 = 0 + 2.2

Combine like terms: -2.2 + 2.2 = 0.0
0.0 + 0.2x + x2 = 0 + 2.2
0.2x + x2 = 0 + 2.2

Combine like terms: 0 + 2.2 = 2.2
0.2x + x2 = 2.2

The x term is 0.2x.  Take half its coefficient (0.1).
Square it (0.01) and add it to both sides.

Add '0.01' to each side of the equation.
0.2x + 0.01 + x2 = 2.2 + 0.01

Reorder the terms:
0.01 + 0.2x + x2 = 2.2 + 0.01

Combine like terms: 2.2 + 0.01 = 2.21
0.01 + 0.2x + x2 = 2.21

Factor a perfect square on the left side:
(x + 0.1)(x + 0.1) = 2.21
