2 the coefficient of the squared term: 

Divide each side by '2'.
231 + 2.5x + x2 = 0

Move the constant term to the right:

Add '-231' to each side of the equation.
231 + 2.5x + -231 + x2 = 0 + -231

Reorder the terms:
231 + -231 + 2.5x + x2 = 0 + -231

Combine like terms: 231 + -231 = 0
0 + 2.5x + x2 = 0 + -231
2.5x + x2 = 0 + -231
