Simplifying
5w2 + -6w + 17 = 8

Reorder the terms:
17 + -6w + 5w2 = 8

Solving
17 + -6w + 5w2 = 8

Solving for variable 'w'.

Reorder the terms:
17 + -8 + -6w + 5w2 = 8 + -8

Combine like terms: 17 + -8 = 9
9 + -6w + 5w2 = 8 + -8

Combine like terms: 8 + -8 = 0
9 + -6w + 5w2 = 0

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

Divide each side by '5'.
1.8 + -1.2w + w2 = 0

Move the constant term to the right:

Add '-1.8' to each side of the equation.
1.8 + -1.2w + -1.8 + w2 = 0 + -1.8

Reorder the terms:
1.8 + -1.8 + -1.2w + w2 = 0 + -1.8

Combine like terms: 1.8 + -1.8 = 0.0
0.0 + -1.2w + w2 = 0 + -1.8
-1.2w + w2 = 0 + -1.8

Combine like terms: 0 + -1.8 = -1.8
-1.2w + w2 = -1.8

The w term is -1.2w.  Take half its coefficient (-0.6).
Square it (0.36) and add it to both sides.

Add '0.36' to each side of the equation.
-1.2w + 0.36 + w2 = -1.8 + 0.36

Reorder the terms:
0.36 + -1.2w + w2 = -1.8 + 0.36

Combine like terms: -1.8 + 0.36 = -1.44
0.36 + -1.2w + w2 = -1.44

Factor a perfect square on the left side:
(w + -0.6)(w + -0.6) = -1.44

Can't calculate square root of the right side.

The solution to this equation could not be determined.
