Begin completing the square.

Move the constant term to the right:

Add '17' to each side of the equation.
-17 + -1n + 17 + n2 = 0 + 17

Reorder the terms:
-17 + 17 + -1n + n2 = 0 + 17

Combine like terms: -17 + 17 = 0
0 + -1n + n2 = 0 + 17
-1n + n2 = 0 + 17

Combine like terms: 0 + 17 = 17
-1n + n2 = 17

The n term is -1n.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1n + 0.25 + n2 = 17 + 0.25

Reorder the terms:
0.25 + -1n + n2 = 17 + 0.25

Combine like terms: 17 + 0.25 = 17.25
0.25 + -1n + n2 = 17.25

Factor a perfect square on the left side:
(n + -0.5)(n + -0.5) = 17.25
