Solution for (4w-8)(w+3)=0 equation:


Simplifying
(4w + -8)(w + 3) = 0

Reorder the terms:
(-8 + 4w)(w + 3) = 0

Reorder the terms:
(-8 + 4w)(3 + w) = 0

Multiply (-8 + 4w) * (3 + w)
(-8(3 + w) + 4w * (3 + w)) = 0
((3 * -8 + w * -8) + 4w * (3 + w)) = 0
((-24 + -8w) + 4w * (3 + w)) = 0
(-24 + -8w + (3 * 4w + w * 4w)) = 0
(-24 + -8w + (12w + 4w2)) = 0

Combine like terms: -8w + 12w = 4w
(-24 + 4w + 4w2) = 0

Solving
-24 + 4w + 4w2 = 0

Subproblem 1

Set the factor '(-3 + -1w)' equal to zero and attempt to solve: Simplifying -3 + -1w = 0 Solving -3 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + -1w = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -1w = 0 + 3 -1w = 0 + 3 Combine like terms: 0 + 3 = 3 -1w = 3 Divide each side by '-1'. w = -3 Simplifying w = -3

Subproblem 2

Set the factor '(2 + -1w)' equal to zero and attempt to solve: Simplifying 2 + -1w = 0 Solving 2 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1w = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1w = 0 + -2 -1w = 0 + -2 Combine like terms: 0 + -2 = -2 -1w = -2 Divide each side by '-1'. w = 2 Simplifying w = 2

Solution

w = {-3, 2}
