Simplifying 9w3 = 81w Solving 9w3 = 81w Solving for variable 'w'. Reorder the terms: -81w + 9w3 = 81w + -81w Combine like terms: 81w + -81w = 0 -81w + 9w3 = 0 Factor out the Greatest Common Factor (GCF), '9w'. 9w(-9 + w2) = 0 Factor a difference between two squares. 9w((3 + w)(-3 + w)) = 0 Ignore the factor 9.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 = 0Subproblem 2
Set the factor '(3 + w)' equal to zero and attempt to solve: Simplifying 3 + w = 0 Solving 3 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + w = 0 + -3 Combine like terms: 3 + -3 = 0 0 + w = 0 + -3 w = 0 + -3 Combine like terms: 0 + -3 = -3 w = -3 Simplifying w = -3Subproblem 3
Set the factor '(-3 + w)' equal to zero and attempt to solve: Simplifying -3 + w = 0 Solving -3 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + w = 0 + 3 Combine like terms: -3 + 3 = 0 0 + w = 0 + 3 w = 0 + 3 Combine like terms: 0 + 3 = 3 w = 3 Simplifying w = 3Solution
w = {0, -3, 3}
