Begin completing the square.

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + -4n + -6 + n2 = 0 + -6

Reorder the terms:
6 + -6 + -4n + n2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -4n + n2 = 0 + -6
-4n + n2 = 0 + -6

Combine like terms: 0 + -6 = -6
-4n + n2 = -6

The n term is -4n.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4n + 4 + n2 = -6 + 4

Reorder the terms:
4 + -4n + n2 = -6 + 4

Combine like terms: -6 + 4 = -2
4 + -4n + n2 = -2
