66 + 3w + w2 = 2(6 + 2w)(w + -1)

Reorder the terms:
66 + 3w + w2 = 2(6 + 2w)(-1 + w)

Multiply (6 + 2w) * (-1 + w)
66 + 3w + w2 = 2(6(-1 + w) + 2w * (-1 + w))
66 + 3w + w2 = 2((-1 * 6 + w * 6) + 2w * (-1 + w))
66 + 3w + w2 = 2((-6 + 6w) + 2w * (-1 + w))
66 + 3w + w2 = 2(-6 + 6w + (-1 * 2w + w * 2w))
66 + 3w + w2 = 2(-6 + 6w + (-2w + 2w2))

Combine like terms: 6w + -2w = 4w
66 + 3w + w2 = 2(-6 + 4w + 2w2)
66 + 3w + w2 = (-6 * 2 + 4w * 2 + 2w2 * 2)
66 + 3w + w2 = (-12 + 8w + 4w2)

Solving
66 + 3w + w2 = -12 + 8w + 4w2

Solving for variable 'w'.

66 + 12 + 3w + -8w + w2 + -4w2 = -12 + 8w + 4w2 + 12 + -8w + -4w2

Combine like terms: 66 + 12 = 78
78 + 3w + -8w + w2 + -4w2 = -12 + 8w + 4w2 + 12 + -8w + -4w2

Combine like terms: 3w + -8w = -5w
78 + -5w + w2 + -4w2 = -12 + 8w + 4w2 + 12 + -8w + -4w2

Combine like terms: w2 + -4w2 = -3w2
78 + -5w + -3w2 = -12 + 8w + 4w2 + 12 + -8w + -4w2

Reorder the terms:
78 + -5w + -3w2 = -12 + 12 + 8w + -8w + 4w2 + -4w2

Combine like terms: -12 + 12 = 0
78 + -5w + -3w2 = 0 + 8w + -8w + 4w2 + -4w2
78 + -5w + -3w2 = 8w + -8w + 4w2 + -4w2

Combine like terms: 8w + -8w = 0
78 + -5w + -3w2 = 0 + 4w2 + -4w2
78 + -5w + -3w2 = 4w2 + -4w2

Combine like terms: 4w2 + -4w2 = 0
78 + -5w + -3w2 = 0
