Solving for variable 'n'.

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

Divide each side by '4'.
12.25 + -3.5n + n2 = 0

Move the constant term to the right:

Add '-12.25' to each side of the equation.
12.25 + -3.5n + -12.25 + n2 = 0 + -12.25

Reorder the terms:
12.25 + -12.25 + -3.5n + n2 = 0 + -12.25

Combine like terms: 12.25 + -12.25 = 0.00
0.00 + -3.5n + n2 = 0 + -12.25
-3.5n + n2 = 0 + -12.25

Combine like terms: 0 + -12.25 = -12.25
-3.5n + n2 = -12.25

The n term is -3.5n.  Take half its coefficient (-1.75).
