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

Divide each side by '8'.
0.625 + -0.875n + n2 = 0

Move the constant term to the right:

Add '-0.625' to each side of the equation.
0.625 + -0.875n + -0.625 + n2 = 0 + -0.625

Reorder the terms:
0.625 + -0.625 + -0.875n + n2 = 0 + -0.625

Combine like terms: 0.625 + -0.625 = 0.000
0.000 + -0.875n + n2 = 0 + -0.625
-0.875n + n2 = 0 + -0.625

Combine like terms: 0 + -0.625 = -0.625
-0.875n + n2 = -0.625

The n term is -0.875n.  Take half its coefficient (-0.4375).
