Simplifying 81r3 + -25r = 0 Reorder the terms: -25r + 81r3 = 0 Solving -25r + 81r3 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), 'r'. r(-25 + 81r2) = 0 Factor a difference between two squares. r((5 + 9r)(-5 + 9r)) = 0Subproblem 1
Set the factor 'r' equal to zero and attempt to solve: Simplifying r = 0 Solving r = 0 Move all terms containing r to the left, all other terms to the right. Simplifying r = 0Subproblem 2
Set the factor '(5 + 9r)' equal to zero and attempt to solve: Simplifying 5 + 9r = 0 Solving 5 + 9r = 0 Move all terms containing r to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + 9r = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 9r = 0 + -5 9r = 0 + -5 Combine like terms: 0 + -5 = -5 9r = -5 Divide each side by '9'. r = -0.5555555556 Simplifying r = -0.5555555556Subproblem 3
Set the factor '(-5 + 9r)' equal to zero and attempt to solve: Simplifying -5 + 9r = 0 Solving -5 + 9r = 0 Move all terms containing r to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + 9r = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 9r = 0 + 5 9r = 0 + 5 Combine like terms: 0 + 5 = 5 9r = 5 Divide each side by '9'. r = 0.5555555556 Simplifying r = 0.5555555556Solution
r = {0, -0.5555555556, 0.5555555556}
