Solution for (5-w)(4w-2)=0 equation:


Simplifying
(5 + -1w)(4w + -2) = 0

Reorder the terms:
(5 + -1w)(-2 + 4w) = 0

Multiply (5 + -1w) * (-2 + 4w)
(5(-2 + 4w) + -1w * (-2 + 4w)) = 0
((-2 * 5 + 4w * 5) + -1w * (-2 + 4w)) = 0
((-10 + 20w) + -1w * (-2 + 4w)) = 0
(-10 + 20w + (-2 * -1w + 4w * -1w)) = 0
(-10 + 20w + (2w + -4w2)) = 0

Combine like terms: 20w + 2w = 22w
(-10 + 22w + -4w2) = 0

Solving
-10 + 22w + -4w2 = 0

Subproblem 1

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

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 = {5, 0.5}
