16 + -1w + -1w2 = 0

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
-16 + w + w2 = 0

Move the constant term to the right:

Add '16' to each side of the equation.
-16 + w + 16 + w2 = 0 + 16

Reorder the terms:
-16 + 16 + w + w2 = 0 + 16

Combine like terms: -16 + 16 = 0
0 + w + w2 = 0 + 16
w + w2 = 0 + 16

Combine like terms: 0 + 16 = 16
w + w2 = 16

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.
 + 0.25 + w2 = 16 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + w2 = 16 + 0.25

Combine like terms: 16 + 0.25 = 16.25
1.25 + w2 = 16.25

Factor a perfect square on the left side:
(w + 0.5)(w + 0.5) = 16.25
