Subproblem 1
Set the factor '(-6 + -4w + w2)' equal to zero and attempt to solve:

Simplifying
-6 + -4w + w2 = 0

Solving
-6 + -4w + w2 = 0

Begin completing the square.

Move the constant term to the right:

Add '6' to each side of the equation.
-6 + -4w + 6 + w2 = 0 + 6

Reorder the terms:
-6 + 6 + -4w + w2 = 0 + 6

Combine like terms: -6 + 6 = 0
0 + -4w + w2 = 0 + 6
-4w + w2 = 0 + 6

Combine like terms: 0 + 6 = 6
-4w + w2 = 6

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

Add '4' to each side of the equation.
-4w + 4 + w2 = 6 + 4

Reorder the terms:
4 + -4w + w2 = 6 + 4

Combine like terms: 6 + 4 = 10
4 + -4w + w2 = 10

Factor a perfect square on the left side:
(w + -2)(w + -2) = 10

Calculate the square root of the right side: 3.16227766

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

Subproblem 1
w + -2 = 3.16227766

Simplifying
w + -2 = 3.16227766

Reorder the terms:
-2 + w = 3.16227766

Solving
-2 + w = 3.16227766

Solving for variable 'w'.

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

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

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

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

Simplifying
w = 5.16227766

Subproblem 2
w + -2 = -3.16227766

Simplifying
w + -2 = -3.16227766

Reorder the terms:
-2 + w = -3.16227766

Solving
-2 + w = -3.16227766

Solving for variable 'w'.

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

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

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

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

Simplifying
w = -1.16227766

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