Solution for (2w-12)(w+9)=0 equation:


Simplifying
(2w + -12)(w + 9) = 0

Reorder the terms:
(-12 + 2w)(w + 9) = 0

Reorder the terms:
(-12 + 2w)(9 + w) = 0

Multiply (-12 + 2w) * (9 + w)
(-12(9 + w) + 2w * (9 + w)) = 0
((9 * -12 + w * -12) + 2w * (9 + w)) = 0
((-108 + -12w) + 2w * (9 + w)) = 0
(-108 + -12w + (9 * 2w + w * 2w)) = 0
(-108 + -12w + (18w + 2w2)) = 0

Combine like terms: -12w + 18w = 6w
(-108 + 6w + 2w2) = 0

Solving
-108 + 6w + 2w2 = 0

Subproblem 1

Set the factor '(-9 + -1w)' equal to zero and attempt to solve: Simplifying -9 + -1w = 0 Solving -9 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + -1w = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -1w = 0 + 9 -1w = 0 + 9 Combine like terms: 0 + 9 = 9 -1w = 9 Divide each side by '-1'. w = -9 Simplifying w = -9

Subproblem 2

Set the factor '(6 + -1w)' equal to zero and attempt to solve: Simplifying 6 + -1w = 0 Solving 6 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + -1w = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1w = 0 + -6 -1w = 0 + -6 Combine like terms: 0 + -6 = -6 -1w = -6 Divide each side by '-1'. w = 6 Simplifying w = 6

Solution

w = {-9, 6}
