5 the coefficient of the squared term: 

Divide each side by '5'.
-0.4 + -2.2x + x2 = 0

Move the constant term to the right:

Add '0.4' to each side of the equation.
-0.4 + -2.2x + 0.4 + x2 = 0 + 0.4

Reorder the terms:
-0.4 + 0.4 + -2.2x + x2 = 0 + 0.4

Combine like terms: -0.4 + 0.4 = 0.0
0.0 + -2.2x + x2 = 0 + 0.4
-2.2x + x2 = 0 + 0.4

Combine like terms: 0 + 0.4 = 0.4
-2.2x + x2 = 0.4

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 = 0.4 + 1.21

Reorder the terms:
1.21 + -2.2x + x2 = 0.4 + 1.21

Combine like terms: 0.4 + 1.21 = 1.61
1.21 + -2.2x + x2 = 1.61

Factor a perfect square on the left side:
(x + -1.1)(x + -1.1) = 1.61
