Solving for variable 'w'.

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

Divide each side by '5'.
-12.6 + 8.8w + w2 = 0

Move the constant term to the right:

Add '12.6' to each side of the equation.
-12.6 + 8.8w + 12.6 + w2 = 0 + 12.6

Reorder the terms:
-12.6 + 12.6 + 8.8w + w2 = 0 + 12.6

Combine like terms: -12.6 + 12.6 = 0.0
0.0 + 8.8w + w2 = 0 + 12.6
8.8w + w2 = 0 + 12.6

Combine like terms: 0 + 12.6 = 12.6
8.8w + w2 = 12.6

The w term is 8.8w.  Take half its coefficient (4.4).
Square it (19.36) and add it to both sides.

Add '19.36' to each side of the equation.
8.8w + 19.36 + w2 = 12.6 + 19.36

Reorder the terms:
19.36 + 8.8w + w2 = 12.6 + 19.36

Combine like terms: 12.6 + 19.36 = 31.96
19.36 + 8.8w + w2 = 31.96

Factor a perfect square on the left side:
(w + 4.4)(w + 4.4) = 31.96
