Combine like terms: 179 + -179 = 0
-179 + -8w + 2w2 = 0

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

Divide each side by '2'.
-89.5 + -4w + w2 = 0

Move the constant term to the right:

Add '89.5' to each side of the equation.
-89.5 + -4w + 89.5 + w2 = 0 + 89.5

Reorder the terms:
-89.5 + 89.5 + -4w + w2 = 0 + 89.5

Combine like terms: -89.5 + 89.5 = 0.0
0.0 + -4w + w2 = 0 + 89.5
-4w + w2 = 0 + 89.5

Combine like terms: 0 + 89.5 = 89.5
-4w + w2 = 89.5

The w term is -4w.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4w + 4 + w2 = 89.5 + 4

Reorder the terms:
4 + -4w + w2 = 89.5 + 4

Combine like terms: 89.5 + 4 = 93.5
4 + -4w + w2 = 93.5
