Simplifying
(3w)(w) = (3w + -2)(w + -2) + 36

Remove parenthesis around (3w)
3w(w) = (3w + -2)(w + -2) + 36

Multiply w * w
3w2 = (3w + -2)(w + -2) + 36

Reorder the terms:
3w2 = (-2 + 3w)(w + -2) + 36

Reorder the terms:
3w2 = (-2 + 3w)(-2 + w) + 36

Multiply (-2 + 3w) * (-2 + w)
3w2 = (-2(-2 + w) + 3w * (-2 + w)) + 36
3w2 = ((-2 * -2 + w * -2) + 3w * (-2 + w)) + 36
3w2 = ((4 + -2w) + 3w * (-2 + w)) + 36
3w2 = (4 + -2w + (-2 * 3w + w * 3w)) + 36
3w2 = (4 + -2w + (-6w + 3w2)) + 36

Combine like terms: -2w + -6w = -8w
3w2 = (4 + -8w + 3w2) + 36

Reorder the terms:
3w2 = 4 + 36 + -8w + 3w2

Combine like terms: 4 + 36 = 40
3w2 = 40 + -8w + 3w2

Add '-3w2' to each side of the equation.
3w2 + -3w2 = 40 + -8w + 3w2 + -3w2

Combine like terms: 3w2 + -3w2 = 0
0 = 40 + -8w + 3w2 + -3w2

Combine like terms: 3w2 + -3w2 = 0
0 = 40 + -8w + 0
0 = 40 + -8w

Solving
0 = 40 + -8w

Solving for variable 'w'.
