1.1 + -1.1 + 1.3x + x2 = 0 + -1.1

Combine like terms: 1.1 + -1.1 = 0.0
0.0 + 1.3x + x2 = 0 + -1.1
1.3x + x2 = 0 + -1.1

Combine like terms: 0 + -1.1 = -1.1
1.3x + x2 = -1.1

The x term is 1.3x.  Take half its coefficient (0.65).
Square it (0.4225) and add it to both sides.

Add '0.4225' to each side of the equation.
1.3x + 0.4225 + x2 = -1.1 + 0.4225
