Solving for variable 'w'.

Begin completing the square.

Move the constant term to the right:

Add '-45' to each side of the equation.
45 + -9w + -45 + w2 = 0 + -45

Reorder the terms:
45 + -45 + -9w + w2 = 0 + -45

Combine like terms: 45 + -45 = 0
0 + -9w + w2 = 0 + -45
-9w + w2 = 0 + -45

-9w + w2 = -45

The w term is -9w.  Take half its coefficient (-4.5).
Square it (20.25) and add it to both sides.

Add '20.25' to each side of the equation.
-9w + 20.25 + w2 = -45 + 20.25

Reorder the terms:
20.25 + -9w + w2 = -45 + 20.25

Combine like terms: -45 + 20.25 = -24.75
20.25 + -9w + w2 = -24.75

Factor a perfect square on the left side:
(w + -4.5)(w + -4.5) = -24.75

Can't calculate square root of the right side.
