114 + 7w + w2 = 2(7 + w)(-3 + w)

Multiply (7 + w) * (-3 + w)
114 + 7w + w2 = 2(7(-3 + w) + w(-3 + w))
114 + 7w + w2 = 2((-3 * 7 + w * 7) + w(-3 + w))
114 + 7w + w2 = 2((-21 + 7w) + w(-3 + w))
114 + 7w + w2 = 2(-21 + 7w + (-3 * w + w * w))
114 + 7w + w2 = 2(-21 + 7w + (-3w + w2))

Combine like terms: 7w + -3w = 4w
114 + 7w + w2 = 2(-21 + 4w + w2)
114 + 7w + w2 = (-21 * 2 + 4w * 2 + w2 * 2)
114 + 7w + w2 = (-42 + 8w + 2w2)

Solving
114 + 7w + w2 = -42 + 8w + 2w2

Combine like terms: 7w + -8w = -1w
156 + -1w + w2 + -2w2 = -42 + 8w + 2w2 + 42 + -8w + -2w2

Combine like terms: w2 + -2w2 = -1w2
156 + -1w + -1w2 = -42 + 8w + 2w2 + 42 + -8w + -2w2

Reorder the terms:
156 + -1w + -1w2 = -42 + 42 + 8w + -8w + 2w2 + -2w2

Combine like terms: -42 + 42 = 0
156 + -1w + -1w2 = 0 + 8w + -8w + 2w2 + -2w2
156 + -1w + -1w2 = 8w + -8w + 2w2 + -2w2

Combine like terms: 8w + -8w = 0
156 + -1w + -1w2 = 0 + 2w2 + -2w2
156 + -1w + -1w2 = 2w2 + -2w2

Combine like terms: 2w2 + -2w2 = 0
156 + -1w + -1w2 = 0

Factor a trinomial.
(12 + -1w)(13 + w) = 0

Subproblem 1

Set the factor '(12 + -1w)' equal to zero and attempt to solve: Simplifying 12 + -1w = 0 Solving 12 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + -1w = 0 + -12 Combine like terms: 12 + -12 = 0 0 + -1w = 0 + -12 -1w = 0 + -12 Combine like terms: 0 + -12 = -12 -1w = -12 Divide each side by '-1'. w = 12 Simplifying w = 12

Subproblem 2

Set the factor '(13 + w)' equal to zero and attempt to solve: Simplifying 13 + w = 0 Solving 13 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + w = 0 + -13 Combine like terms: 13 + -13 = 0 0 + w = 0 + -13 w = 0 + -13 Combine like terms: 0 + -13 = -13 w = -13 Simplifying w = -13

Solution

w = {12, -13}
