26.25 + -26.25 + 0.25x + x2 = 0 + -26.25

Combine like terms: 26.25 + -26.25 = 0.00
0.00 + 0.25x + x2 = 0 + -26.25
0.25x + x2 = 0 + -26.25

Combine like terms: 0 + -26.25 = -26.25
0.25x + x2 = -26.25

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.
0.25x + 0.25 + x2 = -26.25 + 0.25
