0.75 + -0.75 + x + x2 = 0 + -0.75

Combine like terms: 0.75 + -0.75 = 0.00
0.00 + x + x2 = 0 + -0.75
x + x2 = 0 + -0.75

Combine like terms: 0 + -0.75 = -0.75
x + x2 = -0.75

The x term is x.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
 + 0.25 + x2 = -0.75 + 0.25
