Begin completing the square.  Divide all terms by
2 the coefficient of the squared term: 

Divide each side by '2'.
-18.5 + w + w2 = 0

Move the constant term to the right:

Add '18.5' to each side of the equation.
-18.5 + w + 18.5 + w2 = 0 + 18.5

Reorder the terms:
-18.5 + 18.5 + w + w2 = 0 + 18.5

Combine like terms: -18.5 + 18.5 = 0.0
0.0 + w + w2 = 0 + 18.5
w + w2 = 0 + 18.5

Combine like terms: 0 + 18.5 = 18.5
w + w2 = 18.5

The w term is w.  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.
 + 0.25 + w2 = 18.5 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + w2 = 18.5 + 0.25

Combine like terms: 18.5 + 0.25 = 18.75
1.25 + w2 = 18.75

Factor a perfect square on the left side:
(w + 0.5)(w + 0.5) = 18.75

Calculate the square root of the right side: 4.330127019

Break this problem into two subproblems by setting 
(w + 0.5) equal to 4.330127019 and -4.330127019.

Subproblem 1
w + 0.5 = 4.330127019

Simplifying
w + 0.5 = 4.330127019

Reorder the terms:
0.5 + w = 4.330127019

Solving
0.5 + w = 4.330127019

Solving for variable 'w'.

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

Add '-0.5' to each side of the equation.
0.5 + -0.5 + w = 4.330127019 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + w = 4.330127019 + -0.5
w = 4.330127019 + -0.5

Combine like terms: 4.330127019 + -0.5 = 3.830127019
w = 3.830127019

Simplifying
w = 3.830127019

Subproblem 2
w + 0.5 = -4.330127019

Simplifying
w + 0.5 = -4.330127019

Reorder the terms:
0.5 + w = -4.330127019

Solving
0.5 + w = -4.330127019

Solving for variable 'w'.

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

Add '-0.5' to each side of the equation.
0.5 + -0.5 + w = -4.330127019 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + w = -4.330127019 + -0.5
w = -4.330127019 + -0.5

Combine like terms: -4.330127019 + -0.5 = -4.830127019
w = -4.830127019
