Solving for variable 'w'.

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

Divide each side by '2'.
-34 + 0.5w + w2 = 0

Move the constant term to the right:

Add '34' to each side of the equation.
-34 + 0.5w + 34 + w2 = 0 + 34

Reorder the terms:
-34 + 34 + 0.5w + w2 = 0 + 34

Combine like terms: -34 + 34 = 0
0 + 0.5w + w2 = 0 + 34
0.5w + w2 = 0 + 34

Combine like terms: 0 + 34 = 34
0.5w + w2 = 34

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 = 34 + 0.25

Reorder the terms:
0.25 + 0.5w + w2 = 34 + 0.25

Combine like terms: 34 + 0.25 = 34.25
0.25 + 0.5w + w2 = 34.25

Factor a perfect square on the left side:
((w) + 0.5)((w) + 0.5) = 34.25

Calculate the square root of the right side: 5.852349955

Break this problem into two subproblems by setting 
((w) + 0.5) equal to 5.852349955 and -5.852349955.

Subproblem 1

(w) + 0.5 = 5.852349955 Simplifying (w) + 0.5 = 5.852349955 w + 0.5 = 5.852349955 Reorder the terms: 0.5 + w = 5.852349955 Solving 0.5 + w = 5.852349955 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 = 5.852349955 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + w = 5.852349955 + -0.5 w = 5.852349955 + -0.5 Combine like terms: 5.852349955 + -0.5 = 5.352349955 w = 5.352349955 Simplifying w = 5.352349955

Subproblem 2

(w) + 0.5 = -5.852349955 Simplifying (w) + 0.5 = -5.852349955 w + 0.5 = -5.852349955 Reorder the terms: 0.5 + w = -5.852349955 Solving 0.5 + w = -5.852349955 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 = -5.852349955 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + w = -5.852349955 + -0.5 w = -5.852349955 + -0.5 Combine like terms: -5.852349955 + -0.5 = -6.352349955 w = -6.352349955 Simplifying w = -6.352349955
