Solution for -2w(w-9)(w+5)=0 equation:


Simplifying
-2w(w + -9)(w + 5) = 0

Reorder the terms:
-2w(-9 + w)(w + 5) = 0

Reorder the terms:
-2w(-9 + w)(5 + w) = 0

Multiply (-9 + w) * (5 + w)
-2w(-9(5 + w) + w(5 + w)) = 0
-2w((5 * -9 + w * -9) + w(5 + w)) = 0
-2w((-45 + -9w) + w(5 + w)) = 0
-2w(-45 + -9w + (5 * w + w * w)) = 0
-2w(-45 + -9w + (5w + w2)) = 0

Combine like terms: -9w + 5w = -4w
-2w(-45 + -4w + w2) = 0
(-45 * -2w + -4w * -2w + w2 * -2w) = 0
(90w + 8w2 + -2w3) = 0

Solving
90w + 8w2 + -2w3 = 0

Solving for variable 'w'.

Factor out the Greatest Common Factor (GCF), '2w'.

Subproblem 1

Set the factor 'w' equal to zero and attempt to solve: Simplifying w = 0 Solving w = 0 Move all terms containing w to the left, all other terms to the right. Simplifying w = 0

Subproblem 2

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 3

Set the factor '(5 + w)' equal to zero and attempt to solve: Simplifying 5 + w = 0 Solving 5 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + w = 0 + -5 Combine like terms: 5 + -5 = 0 0 + w = 0 + -5 w = 0 + -5 Combine like terms: 0 + -5 = -5 w = -5 Simplifying w = -5

Solution

w = {0, 9, -5}
