Solving for variable 'w'.

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

Divide each side by '4'.
43.75 + 15w + w2 = 0

Move the constant term to the right:

Add '-43.75' to each side of the equation.
43.75 + 15w + -43.75 + w2 = 0 + -43.75

Reorder the terms:
43.75 + -43.75 + 15w + w2 = 0 + -43.75

Combine like terms: 43.75 + -43.75 = 0.00
0.00 + 15w + w2 = 0 + -43.75
15w + w2 = 0 + -43.75

Combine like terms: 0 + -43.75 = -43.75
15w + w2 = -43.75

The w term is 15w.  Take half its coefficient (7.5).
Square it (56.25) and add it to both sides.

Add '56.25' to each side of the equation.
15w + 56.25 + w2 = -43.75 + 56.25

Reorder the terms:
56.25 + 15w + w2 = -43.75 + 56.25

Combine like terms: -43.75 + 56.25 = 12.5
56.25 + 15w + w2 = 12.5

Factor a perfect square on the left side:
(w + 7.5)(w + 7.5) = 12.5

Calculate the square root of the right side: 3.535533906

Break this problem into two subproblems by setting 
(w + 7.5) equal to 3.535533906 and -3.535533906.

Subproblem 1

w + 7.5 = 3.535533906 Simplifying w + 7.5 = 3.535533906 Reorder the terms: 7.5 + w = 3.535533906 Solving 7.5 + w = 3.535533906 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + w = 3.535533906 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + w = 3.535533906 + -7.5 w = 3.535533906 + -7.5 Combine like terms: 3.535533906 + -7.5 = -3.964466094 w = -3.964466094 Simplifying w = -3.964466094

Subproblem 2

w + 7.5 = -3.535533906 Simplifying w + 7.5 = -3.535533906 Reorder the terms: 7.5 + w = -3.535533906 Solving 7.5 + w = -3.535533906 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + w = -3.535533906 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + w = -3.535533906 + -7.5 w = -3.535533906 + -7.5 Combine like terms: -3.535533906 + -7.5 = -11.035533906 w = -11.035533906 Simplifying w = -11.035533906
