Simplifying 80r3 + 52r2 + -60r = 0 Reorder the terms: -60r + 52r2 + 80r3 = 0 Solving -60r + 52r2 + 80r3 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), '4r'. 4r(-15 + 13r + 20r2) = 0 Factor a trinomial. 4r((-5 + -4r)(3 + -5r)) = 0 Ignore the factor 4.Subproblem 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 + -4r)' equal to zero and attempt to solve: Simplifying -5 + -4r = 0 Solving -5 + -4r = 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 + -4r = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -4r = 0 + 5 -4r = 0 + 5 Combine like terms: 0 + 5 = 5 -4r = 5 Divide each side by '-4'. r = -1.25 Simplifying r = -1.25Subproblem 3
Set the factor '(3 + -5r)' equal to zero and attempt to solve: Simplifying 3 + -5r = 0 Solving 3 + -5r = 0 Move all terms containing r to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -5r = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -5r = 0 + -3 -5r = 0 + -3 Combine like terms: 0 + -3 = -3 -5r = -3 Divide each side by '-5'. r = 0.6 Simplifying r = 0.6Solution
r = {0, -1.25, 0.6}
