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

Divide each side by '-5'.
112 + -2.2x + x2 = 0

Move the constant term to the right:

Add '-112' to each side of the equation.
112 + -2.2x + -112 + x2 = 0 + -112

Reorder the terms:
112 + -112 + -2.2x + x2 = 0 + -112

Combine like terms: 112 + -112 = 0
0 + -2.2x + x2 = 0 + -112
-2.2x + x2 = 0 + -112

Combine like terms: 0 + -112 = -112
-2.2x + x2 = -112

The x term is -2.2x.  Take half its coefficient (-1.1).
Square it (1.21) and add it to both sides.
