Simplifying
-4w(w + -1)(w + 5) = 0

Reorder the terms:
-4w(-1 + w)(w + 5) = 0

Reorder the terms:
-4w(-1 + w)(5 + w) = 0

Multiply (-1 + w) * (5 + w)
-4w(-1(5 + w) + w(5 + w)) = 0
-4w((5 * -1 + w * -1) + w(5 + w)) = 0
-4w((-5 + -1w) + w(5 + w)) = 0
-4w(-5 + -1w + (5 * w + w * w)) = 0
-4w(-5 + -1w + (5w + w2)) = 0

Combine like terms: -1w + 5w = 4w
-4w(-5 + 4w + w2) = 0
(-5 * -4w + 4w * -4w + w2 * -4w) = 0
(20w + -16w2 + -4w3) = 0

Solving
20w + -16w2 + -4w3 = 0

Solving for variable 'w'.

Factor out the Greatest Common Factor (GCF), '4w'.

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

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, 1, -5}
