Simplifying 15r3 + -15rs = 0 Reorder the terms: -15rs + 15r3 = 0 Solving -15rs + 15r3 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), '15r'. 15r(-1s + r2) = 0 Ignore the factor 15.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 '(-1s + r2)' equal to zero and attempt to solve: Simplifying -1s + r2 = 0 Reorder the terms: r2 + -1s = 0 Solving r2 + -1s = 0 Move all terms containing r to the left, all other terms to the right. Add 's' to each side of the equation. r2 + -1s + s = 0 + s Combine like terms: -1s + s = 0 r2 + 0 = 0 + s r2 = 0 + s Remove the zero: r2 = s Simplifying r2 = s The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
