(30w + w2) = 3600

Solving
30w + w2 = 3600

Solving for variable 'w'.

Reorder the terms:
-3600 + 30w + w2 = 3600 + -3600

Combine like terms: 3600 + -3600 = 0
-3600 + 30w + w2 = 0

Begin completing the square.

Move the constant term to the right:

Add '3600' to each side of the equation.
-3600 + 30w + 3600 + w2 = 0 + 3600

Reorder the terms:
-3600 + 3600 + 30w + w2 = 0 + 3600

Combine like terms: -3600 + 3600 = 0
0 + 30w + w2 = 0 + 3600
30w + w2 = 0 + 3600

Combine like terms: 0 + 3600 = 3600
30w + w2 = 3600

The w term is 30w.  Take half its coefficient (15).
Square it (225) and add it to both sides.

Add '225' to each side of the equation.
30w + 225 + w2 = 3600 + 225
