8 the coefficient of the squared term: 

Divide each side by '8'.
1.125 + -2.5x + x2 = 0

Move the constant term to the right:

Add '-1.125' to each side of the equation.
1.125 + -2.5x + -1.125 + x2 = 0 + -1.125

Reorder the terms:
1.125 + -1.125 + -2.5x + x2 = 0 + -1.125

Combine like terms: 1.125 + -1.125 = 0.000
0.000 + -2.5x + x2 = 0 + -1.125
-2.5x + x2 = 0 + -1.125

Combine like terms: 0 + -1.125 = -1.125
-2.5x + x2 = -1.125

The x term is -2.5x.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5x + 1.5625 + x2 = -1.125 + 1.5625
