Solving for variable 'w'.

Begin completing the square.  Divide all terms by
-10 the coefficient of the squared term: 

Divide each side by '-10'.
-0.5 + -2.7w + w2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + -2.7w + 0.5 + w2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + -2.7w + w2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + -2.7w + w2 = 0 + 0.5
-2.7w + w2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
-2.7w + w2 = 0.5

The w term is -2.7w.  Take half its coefficient (-1.35).
Square it (1.8225) and add it to both sides.

Add '1.8225' to each side of the equation.
-2.7w + 1.8225 + w2 = 0.5 + 1.8225

Reorder the terms:
1.8225 + -2.7w + w2 = 0.5 + 1.8225

Combine like terms: 0.5 + 1.8225 = 2.3225
1.8225 + -2.7w + w2 = 2.3225

Factor a perfect square on the left side:
(w + -1.35)(w + -1.35) = 2.3225

Calculate the square root of the right side: 1.523975065
