Ignore the factor -1.
Subproblem 1
Set the factor '(4 + 6x + x2)' equal to zero and attempt to solve:

Simplifying
4 + 6x + x2 = 0

Solving
4 + 6x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-4' to each side of the equation.
4 + 6x + -4 + x2 = 0 + -4

Reorder the terms:
4 + -4 + 6x + x2 = 0 + -4

Combine like terms: 4 + -4 = 0
0 + 6x + x2 = 0 + -4
6x + x2 = 0 + -4

Combine like terms: 0 + -4 = -4
6x + x2 = -4

The x term is 6x.  Take half its coefficient (3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
6x + 9 + x2 = -4 + 9

Reorder the terms:
9 + 6x + x2 = -4 + 9

Combine like terms: -4 + 9 = 5
9 + 6x + x2 = 5

Factor a perfect square on the left side:
(x + 3)(x + 3) = 5

Calculate the square root of the right side: 2.236067978
