Solving for variable 'w'.

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

Divide each side by '2'.
-22 + 2.5w + w2 = 0

Move the constant term to the right:

Add '22' to each side of the equation.
-22 + 2.5w + 22 + w2 = 0 + 22

Reorder the terms:
-22 + 22 + 2.5w + w2 = 0 + 22

Combine like terms: -22 + 22 = 0
0 + 2.5w + w2 = 0 + 22
2.5w + w2 = 0 + 22

Combine like terms: 0 + 22 = 22
2.5w + w2 = 22

The w term is 2.5w.  Take half its coefficient (1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
2.5w + 1.5625 + w2 = 22 + 1.5625

Reorder the terms:
1.5625 + 2.5w + w2 = 22 + 1.5625

Combine like terms: 22 + 1.5625 = 23.5625
1.5625 + 2.5w + w2 = 23.5625

Factor a perfect square on the left side:
(w + 1.25)(w + 1.25) = 23.5625

Calculate the square root of the right side: 4.85412196

Break this problem into two subproblems by setting 
(w + 1.25) equal to 4.85412196 and -4.85412196.

Subproblem 1

w + 1.25 = 4.85412196 Simplifying w + 1.25 = 4.85412196 Reorder the terms: 1.25 + w = 4.85412196 Solving 1.25 + w = 4.85412196 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + w = 4.85412196 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + w = 4.85412196 + -1.25 w = 4.85412196 + -1.25 Combine like terms: 4.85412196 + -1.25 = 3.60412196 w = 3.60412196 Simplifying w = 3.60412196

Subproblem 2

w + 1.25 = -4.85412196 Simplifying w + 1.25 = -4.85412196 Reorder the terms: 1.25 + w = -4.85412196 Solving 1.25 + w = -4.85412196 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + w = -4.85412196 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + w = -4.85412196 + -1.25 w = -4.85412196 + -1.25 Combine like terms: -4.85412196 + -1.25 = -6.10412196 w = -6.10412196 Simplifying w = -6.10412196

Solution
