Solving for variable 'w'.

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

Divide each side by '2'.
-44 + 0.5w + w2 = 0

Move the constant term to the right:

Add '44' to each side of the equation.
-44 + 0.5w + 44 + w2 = 0 + 44

Reorder the terms:
-44 + 44 + 0.5w + w2 = 0 + 44

Combine like terms: -44 + 44 = 0
0 + 0.5w + w2 = 0 + 44
0.5w + w2 = 0 + 44

Combine like terms: 0 + 44 = 44
0.5w + w2 = 44

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.
0.5w + 0.25 + w2 = 44 + 0.25

Reorder the terms:
0.25 + 0.5w + w2 = 44 + 0.25

Combine like terms: 44 + 0.25 = 44.25
0.25 + 0.5w + w2 = 44.25

Factor a perfect square on the left side:
(w + 0.5)(w + 0.5) = 44.25

Calculate the square root of the right side: 6.652067348

Break this problem into two subproblems by setting 
(w + 0.5) equal to 6.652067348 and -6.652067348.

Subproblem 1

w + 0.5 = 6.652067348 Simplifying w + 0.5 = 6.652067348 Reorder the terms: 0.5 + w = 6.652067348 Solving 0.5 + w = 6.652067348 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 = 6.652067348 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + w = 6.652067348 + -0.5 w = 6.652067348 + -0.5 Combine like terms: 6.652067348 + -0.5 = 6.152067348 w = 6.152067348 Simplifying w = 6.152067348

Subproblem 2

w + 0.5 = -6.652067348 Simplifying w + 0.5 = -6.652067348 Reorder the terms: 0.5 + w = -6.652067348 Solving 0.5 + w = -6.652067348 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 = -6.652067348 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + w = -6.652067348 + -0.5 w = -6.652067348 + -0.5 Combine like terms: -6.652067348 + -0.5 = -7.152067348 w = -7.152067348 Simplifying w = -7.152067348
