Solving for variable 'n'.

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

Divide each side by '8'.
0.5 + -0.625n + n2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -0.625n + -0.5 + n2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -0.625n + n2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -0.625n + n2 = 0 + -0.5
-0.625n + n2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-0.625n + n2 = -0.5

The n term is -0.625n.  Take half its coefficient (-0.3125).
