Ignore the factor 2.
Subproblem 1
Set the factor '(3 + -1n + n2)' equal to zero and attempt to solve:

Simplifying
3 + -1n + n2 = 0

Solving
3 + -1n + n2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -1n + -3 + n2 = 0 + -3

Reorder the terms:
3 + -3 + -1n + n2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1n + n2 = 0 + -3
-1n + n2 = 0 + -3

Combine like terms: 0 + -3 = -3
-1n + n2 = -3

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 = -3 + 0.25

Reorder the terms:
0.25 + -1n + n2 = -3 + 0.25

Combine like terms: -3 + 0.25 = -2.75
0.25 + -1n + n2 = -2.75

Factor a perfect square on the left side:
(n + -0.5)(n + -0.5) = -2.75

Can't calculate square root of the right side.
