5 + -5n + 4n2 = 0

Solving for variable 'n'.

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

Divide each side by '4'.
1.25 + -1.25n + n2 = 0

Move the constant term to the right:

Add '-1.25' to each side of the equation.
1.25 + -1.25n + -1.25 + n2 = 0 + -1.25

Reorder the terms:
1.25 + -1.25 + -1.25n + n2 = 0 + -1.25

Combine like terms: 1.25 + -1.25 = 0.00
0.00 + -1.25n + n2 = 0 + -1.25
-1.25n + n2 = 0 + -1.25

Combine like terms: 0 + -1.25 = -1.25
-1.25n + n2 = -1.25

The n term is -1.25n.  Take half its coefficient (-0.625).
Square it (0.390625) and add it to both sides.

Add '0.390625' to each side of the equation.
-1.25n + 0.390625 + n2 = -1.25 + 0.390625

Reorder the terms:
0.390625 + -1.25n + n2 = -1.25 + 0.390625

Combine like terms: -1.25 + 0.390625 = -0.859375
0.390625 + -1.25n + n2 = -0.859375
