-13 + 6w + -8w2 = 0

Solving for variable 'w'.

Begin completing the square.  Divide all terms by
-8 the coefficient of the squared term: 

Divide each side by '-8'.
1.625 + -0.75w + w2 = 0

Move the constant term to the right:

Add '-1.625' to each side of the equation.
1.625 + -0.75w + -1.625 + w2 = 0 + -1.625

Reorder the terms:
1.625 + -1.625 + -0.75w + w2 = 0 + -1.625

Combine like terms: 1.625 + -1.625 = 0.000
0.000 + -0.75w + w2 = 0 + -1.625
-0.75w + w2 = 0 + -1.625

Combine like terms: 0 + -1.625 = -1.625
-0.75w + w2 = -1.625

The w term is -0.75w.  Take half its coefficient (-0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
-0.75w + 0.140625 + w2 = -1.625 + 0.140625

Reorder the terms:
0.140625 + -0.75w + w2 = -1.625 + 0.140625

Combine like terms: -1.625 + 0.140625 = -1.484375
0.140625 + -0.75w + w2 = -1.484375

Factor a perfect square on the left side:
(w + -0.375)(w + -0.375) = -1.484375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
