1.5 + -1.5 + -1.3x + x2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + -1.3x + x2 = 0 + -1.5
-1.3x + x2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
-1.3x + x2 = -1.5

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 = -1.5 + 0.4225
