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


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

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

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

Multiply (8 + w) * (-4 + w)
(8(-4 + w) + w(-4 + w)) = 0
((-4 * 8 + w * 8) + w(-4 + w)) = 0
((-32 + 8w) + w(-4 + w)) = 0
(-32 + 8w + (-4 * w + w * w)) = 0
(-32 + 8w + (-4w + w2)) = 0

Combine like terms: 8w + -4w = 4w
(-32 + 4w + w2) = 0

Solving
-32 + 4w + w2 = 0

Solving for variable 'w'.

Factor a trinomial.

Subproblem 1

Set the factor '(-8 + -1w)' equal to zero and attempt to solve: Simplifying -8 + -1w = 0 Solving -8 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + -1w = 0 + 8 Combine like terms: -8 + 8 = 0 0 + -1w = 0 + 8 -1w = 0 + 8 Combine like terms: 0 + 8 = 8 -1w = 8 Divide each side by '-1'. w = -8 Simplifying w = -8

Subproblem 2

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

Solution

w = {-8, 4}
