Reorder the terms:
2.24 + -2.24 + 2.2x + x2 = 0 + -2.24

Combine like terms: 2.24 + -2.24 = 0.00
0.00 + 2.2x + x2 = 0 + -2.24
2.2x + x2 = 0 + -2.24

Combine like terms: 0 + -2.24 = -2.24
2.2x + x2 = -2.24

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 = -2.24 + 1.21
