Simplifying r3 + -2r3 + -8r = 0 Reorder the terms: -8r + r3 + -2r3 = 0 Combine like terms: r3 + -2r3 = -1r3 -8r + -1r3 = 0 Solving -8r + -1r3 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), '-1r'. -1r(8 + r2) = 0 Ignore the factor -1.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 '(8 + r2)' equal to zero and attempt to solve: Simplifying 8 + r2 = 0 Solving 8 + r2 = 0 Move all terms containing r to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + r2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + r2 = 0 + -8 r2 = 0 + -8 Combine like terms: 0 + -8 = -8 r2 = -8 Simplifying r2 = -8 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
