Solving for variable 'n'.

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

Divide each side by '5'.
112.8 + 1.4n + n2 = 0

Move the constant term to the right:

Add '-112.8' to each side of the equation.
112.8 + 1.4n + -112.8 + n2 = 0 + -112.8

Reorder the terms:
112.8 + -112.8 + 1.4n + n2 = 0 + -112.8

Combine like terms: 112.8 + -112.8 = 0.0
0.0 + 1.4n + n2 = 0 + -112.8
1.4n + n2 = 0 + -112.8

Combine like terms: 0 + -112.8 = -112.8
1.4n + n2 = -112.8

The n term is 1.4n.  Take half its coefficient (0.7).
Square it (0.49) and add it to both sides.

Add '0.49' to each side of the equation.
1.4n + 0.49 + n2 = -112.8 + 0.49

Reorder the terms:
0.49 + 1.4n + n2 = -112.8 + 0.49

Combine like terms: -112.8 + 0.49 = -112.31
0.49 + 1.4n + n2 = -112.31

Factor a perfect square on the left side:
(n + 0.7)(n + 0.7) = -112.31

Can't calculate square root of the right side.
