8 the coefficient of the squared term: 

Divide each side by '8'.
1 + 0.375n + n2 = 0

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + 0.375n + -1 + n2 = 0 + -1

Reorder the terms:
1 + -1 + 0.375n + n2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 0.375n + n2 = 0 + -1
0.375n + n2 = 0 + -1

Combine like terms: 0 + -1 = -1
0.375n + n2 = -1

The n term is 0.375n.  Take half its coefficient (0.1875).
