Simplifying
(4 + w)(4w + -2) = 0

Reorder the terms:
(4 + w)(-2 + 4w) = 0

Multiply (4 + w) * (-2 + 4w)
(4(-2 + 4w) + w(-2 + 4w)) = 0
((-2 * 4 + 4w * 4) + w(-2 + 4w)) = 0
((-8 + 16w) + w(-2 + 4w)) = 0
(-8 + 16w + (-2 * w + 4w * w)) = 0
(-8 + 16w + (-2w + 4w2)) = 0

Combine like terms: 16w + -2w = 14w
(-8 + 14w + 4w2) = 0

Solving
-8 + 14w + 4w2 = 0

Subproblem 1

Set the factor '(-4 + -1w)' equal to zero and attempt to solve: Simplifying -4 + -1w = 0 Solving -4 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + -1w = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -1w = 0 + 4 -1w = 0 + 4 Combine like terms: 0 + 4 = 4 -1w = 4 Divide each side by '-1'. w = -4 Simplifying w = -4

Subproblem 2

Set the factor '(1 + -2w)' equal to zero and attempt to solve: Simplifying 1 + -2w = 0 Solving 1 + -2w = 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 + -2w = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2w = 0 + -1 -2w = 0 + -1 Combine like terms: 0 + -1 = -1 -2w = -1 Divide each side by '-2'. w = 0.5 Simplifying w = 0.5

Solution

w = {-4, 0.5}
