Solving for variable 'n'.

Begin completing the square.  Divide all terms by
2 the coefficient of the squared term: 

Divide each side by '2'.
3 + -2.5n + n2 = 0

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -2.5n + -3 + n2 = 0 + -3

Reorder the terms:
3 + -3 + -2.5n + n2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -2.5n + n2 = 0 + -3
-2.5n + n2 = 0 + -3
