Simplifying
5w2 = -9w + -5

Reorder the terms:
5w2 = -5 + -9w

Solving
5w2 = -5 + -9w

Solving for variable 'w'.

Reorder the terms:
5 + 9w + 5w2 = -5 + -9w + 5 + 9w

Reorder the terms:
5 + 9w + 5w2 = -5 + 5 + -9w + 9w

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

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

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

Divide each side by '5'.
1 + 1.8w + w2 = 0

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + 1.8w + -1 + w2 = 0 + -1

Reorder the terms:
1 + -1 + 1.8w + w2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 1.8w + w2 = 0 + -1
1.8w + w2 = 0 + -1

Combine like terms: 0 + -1 = -1
1.8w + w2 = -1

The w term is 1.8w.  Take half its coefficient (0.9).
Square it (0.81) and add it to both sides.

Add '0.81' to each side of the equation.
1.8w + 0.81 + w2 = -1 + 0.81

Reorder the terms:
0.81 + 1.8w + w2 = -1 + 0.81

Combine like terms: -1 + 0.81 = -0.19
0.81 + 1.8w + w2 = -0.19

Factor a perfect square on the left side:
(w + 0.9)(w + 0.9) = -0.19

Can't calculate square root of the right side.

The solution to this equation could not be determined.
