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

Break this problem into two subproblems by setting 
(n + -2) equal to 3.16227766 and -3.16227766.

Subproblem 1
n + -2 = 3.16227766

Simplifying
n + -2 = 3.16227766

Reorder the terms:
-2 + n = 3.16227766

Solving
-2 + n = 3.16227766

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '2' to each side of the equation.
-2 + 2 + n = 3.16227766 + 2

Combine like terms: -2 + 2 = 0
0 + n = 3.16227766 + 2
n = 3.16227766 + 2

Combine like terms: 3.16227766 + 2 = 5.16227766
n = 5.16227766

Simplifying
n = 5.16227766

Subproblem 2
n + -2 = -3.16227766

Simplifying
n + -2 = -3.16227766

Reorder the terms:
-2 + n = -3.16227766

Solving
-2 + n = -3.16227766

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '2' to each side of the equation.
-2 + 2 + n = -3.16227766 + 2

Combine like terms: -2 + 2 = 0
0 + n = -3.16227766 + 2
n = -3.16227766 + 2

Combine like terms: -3.16227766 + 2 = -1.16227766
n = -1.16227766

Simplifying
n = -1.16227766

Solution
The solution to the problem is based on the solutions
from the subproblems.
n = {5.16227766, -1.16227766}
