-88 + 5w + -2w2 = 0

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

Divide each side by '-2'.
44 + -2.5w + w2 = 0

Move the constant term to the right:

Add '-44' to each side of the equation.
44 + -2.5w + -44 + w2 = 0 + -44

Reorder the terms:
44 + -44 + -2.5w + w2 = 0 + -44

Combine like terms: 44 + -44 = 0
0 + -2.5w + w2 = 0 + -44
-2.5w + w2 = 0 + -44

Combine like terms: 0 + -44 = -44
-2.5w + w2 = -44

The w term is -2.5w.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5w + 1.5625 + w2 = -44 + 1.5625

Reorder the terms:
1.5625 + -2.5w + w2 = -44 + 1.5625

Combine like terms: -44 + 1.5625 = -42.4375
1.5625 + -2.5w + w2 = -42.4375

Factor a perfect square on the left side:
(w + -1.25)(w + -1.25) = -42.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
