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

Divide each side by '5'.
2.4 + -2.4n + n2 = 0

Move the constant term to the right:

Add '-2.4' to each side of the equation.
2.4 + -2.4n + -2.4 + n2 = 0 + -2.4

Reorder the terms:
2.4 + -2.4 + -2.4n + n2 = 0 + -2.4

Combine like terms: 2.4 + -2.4 = 0.0
0.0 + -2.4n + n2 = 0 + -2.4
-2.4n + n2 = 0 + -2.4
