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

Divide each side by '5'.
-4.4 + 0.6x + x2 = 0

Move the constant term to the right:

Add '4.4' to each side of the equation.
-4.4 + 0.6x + 4.4 + x2 = 0 + 4.4

Reorder the terms:
-4.4 + 4.4 + 0.6x + x2 = 0 + 4.4

Combine like terms: -4.4 + 4.4 = 0.0
0.0 + 0.6x + x2 = 0 + 4.4
0.6x + x2 = 0 + 4.4

Combine like terms: 0 + 4.4 = 4.4
0.6x + x2 = 4.4

The x term is 0.6x.  Take half its coefficient (0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
0.6x + 0.09 + x2 = 4.4 + 0.09
