-0.4 + 0.4 + 1.1x + x2 = 0 + 0.4

Combine like terms: -0.4 + 0.4 = 0.0
0.0 + 1.1x + x2 = 0 + 0.4
1.1x + x2 = 0 + 0.4

Combine like terms: 0 + 0.4 = 0.4
1.1x + x2 = 0.4

The x term is 1.1x.  Take half its coefficient (0.55).
Square it (0.3025) and add it to both sides.

Add '0.3025' to each side of the equation.
1.1x + 0.3025 + x2 = 0.4 + 0.3025
