Solution for =2(w^2+2w-168) equation:


Simplifying
0 = 2(w2 + 2w + -168)

Reorder the terms:
0 = 2(-168 + 2w + w2)
0 = (-168 * 2 + 2w * 2 + w2 * 2)
0 = (-336 + 4w + 2w2)

Solving
0 = -336 + 4w + 2w2

Solving for variable 'w'.

Combine like terms: 0 + 336 = 336
336 + -4w + -2w2 = -336 + 4w + 2w2 + 336 + -4w + -2w2

Reorder the terms:
336 + -4w + -2w2 = -336 + 336 + 4w + -4w + 2w2 + -2w2

Combine like terms: -336 + 336 = 0
336 + -4w + -2w2 = 0 + 4w + -4w + 2w2 + -2w2
336 + -4w + -2w2 = 4w + -4w + 2w2 + -2w2

Combine like terms: 4w + -4w = 0
336 + -4w + -2w2 = 0 + 2w2 + -2w2
336 + -4w + -2w2 = 2w2 + -2w2

Combine like terms: 2w2 + -2w2 = 0
336 + -4w + -2w2 = 0

Factor a trinomial.
2((12 + -1w)(14 + w)) = 0

Ignore the factor 2.

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 '(14 + w)' equal to zero and attempt to solve: Simplifying 14 + w = 0 Solving 14 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + w = 0 + -14 Combine like terms: 14 + -14 = 0 0 + w = 0 + -14 w = 0 + -14 Combine like terms: 0 + -14 = -14 w = -14 Simplifying w = -14

Solution

w = {12, -14}
