Simplifying 2r6 = 8r4 Solving 2r6 = 8r4 Solving for variable 'r'. Reorder the terms: -8r4 + 2r6 = 8r4 + -8r4 Combine like terms: 8r4 + -8r4 = 0 -8r4 + 2r6 = 0 Factor out the Greatest Common Factor (GCF), '2r4'. 2r4(-4 + r2) = 0 Factor a difference between two squares. 2r4((2 + r)(-2 + r)) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'r4' equal to zero and attempt to solve: Simplifying r4 = 0 Solving r4 = 0 Move all terms containing r to the left, all other terms to the right. Simplifying r4 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(2 + r)' equal to zero and attempt to solve: Simplifying 2 + r = 0 Solving 2 + r = 0 Move all terms containing r to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + r = 0 + -2 Combine like terms: 2 + -2 = 0 0 + r = 0 + -2 r = 0 + -2 Combine like terms: 0 + -2 = -2 r = -2 Simplifying r = -2Subproblem 3
Set the factor '(-2 + r)' equal to zero and attempt to solve: Simplifying -2 + r = 0 Solving -2 + r = 0 Move all terms containing r to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + r = 0 + 2 Combine like terms: -2 + 2 = 0 0 + r = 0 + 2 r = 0 + 2 Combine like terms: 0 + 2 = 2 r = 2 Simplifying r = 2Solution
r = {-2, 2}
