Solving for variable 'w'.

Begin completing the square.

Move the constant term to the right:

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

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

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

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

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

Add '9' to each side of the equation.
-6w + 9 + w2 = -6 + 9

Reorder the terms:
9 + -6w + w2 = -6 + 9

Combine like terms: -6 + 9 = 3
9 + -6w + w2 = 3

Factor a perfect square on the left side:
(w + -3)(w + -3) = 3

Calculate the square root of the right side: 1.732050808

Break this problem into two subproblems by setting 
(w + -3) equal to 1.732050808 and -1.732050808.

Subproblem 1
w + -3 = 1.732050808

Simplifying
w + -3 = 1.732050808

Reorder the terms:
-3 + w = 1.732050808

Solving
-3 + w = 1.732050808

Solving for variable 'w'.

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

Add '3' to each side of the equation.
-3 + 3 + w = 1.732050808 + 3

Combine like terms: -3 + 3 = 0
0 + w = 1.732050808 + 3
w = 1.732050808 + 3

Combine like terms: 1.732050808 + 3 = 4.732050808
w = 4.732050808

Simplifying
w = 4.732050808

Subproblem 2
w + -3 = -1.732050808

Simplifying
w + -3 = -1.732050808

Reorder the terms:
-3 + w = -1.732050808

Solving
-3 + w = -1.732050808

Solving for variable 'w'.

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

Add '3' to each side of the equation.
-3 + 3 + w = -1.732050808 + 3

Combine like terms: -3 + 3 = 0
0 + w = -1.732050808 + 3
w = -1.732050808 + 3

Combine like terms: -1.732050808 + 3 = 1.267949192
w = 1.267949192

Simplifying
w = 1.267949192

Solution
The solution to the problem is based on the solutions
from the subproblems.
w = {4.732050808, 1.267949192}
