Simplifying 2r2 + -2r5 = 0 Solving 2r2 + -2r5 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), '2r2'. 2r2(1 + -1r3) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'r2' equal to zero and attempt to solve: Simplifying r2 = 0 Solving r2 = 0 Move all terms containing r to the left, all other terms to the right. Simplifying r2 = 0 Take the square root of each side: r = {0}Subproblem 2
Set the factor '(1 + -1r3)' equal to zero and attempt to solve: Simplifying 1 + -1r3 = 0 Solving 1 + -1r3 = 0 Move all terms containing r to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1r3 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1r3 = 0 + -1 -1r3 = 0 + -1 Combine like terms: 0 + -1 = -1 -1r3 = -1 Divide each side by '-1'. r3 = 1 Simplifying r3 = 1 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
