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

Divide each side by '5'.
13.8 + 4.4x + x2 = 0

Move the constant term to the right:

Add '-13.8' to each side of the equation.
13.8 + 4.4x + -13.8 + x2 = 0 + -13.8

Reorder the terms:
13.8 + -13.8 + 4.4x + x2 = 0 + -13.8

Combine like terms: 13.8 + -13.8 = 0.0
0.0 + 4.4x + x2 = 0 + -13.8
4.4x + x2 = 0 + -13.8

Combine like terms: 0 + -13.8 = -13.8
4.4x + x2 = -13.8

The x term is 4.4x.  Take half its coefficient (2.2).
Square it (4.84) and add it to both sides.

Add '4.84' to each side of the equation.
4.4x + 4.84 + x2 = -13.8 + 4.84

Reorder the terms:
4.84 + 4.4x + x2 = -13.8 + 4.84

Combine like terms: -13.8 + 4.84 = -8.96
4.84 + 4.4x + x2 = -8.96

Factor a perfect square on the left side:
(x + 2.2)(x + 2.2) = -8.96

Can't calculate square root of the right side.
