Add '-72' to each side of the equation.
72 + 136w + -72 + 9w2 = 72 + 73w + -72 + 8w2

Reorder the terms:
72 + -72 + 136w + 9w2 = 72 + 73w + -72 + 8w2

Combine like terms: 72 + -72 = 0
0 + 136w + 9w2 = 72 + 73w + -72 + 8w2
136w + 9w2 = 72 + 73w + -72 + 8w2

Reorder the terms:
136w + 9w2 = 72 + -72 + 73w + 8w2

Combine like terms: 72 + -72 = 0
136w + 9w2 = 0 + 73w + 8w2
136w + 9w2 = 73w + 8w2

Solving
136w + 9w2 = 73w + 8w2

Solving for variable 'w'.

Reorder the terms:
136w + -73w + 9w2 + -8w2 = 73w + 8w2 + -73w + -8w2

Combine like terms: 136w + -73w = 63w
63w + 9w2 + -8w2 = 73w + 8w2 + -73w + -8w2

Combine like terms: 9w2 + -8w2 = 1w2
63w + 1w2 = 73w + 8w2 + -73w + -8w2
