Simplifying 28r3 = 63r Solving 28r3 = 63r Solving for variable 'r'. Reorder the terms: -63r + 28r3 = 63r + -63r Combine like terms: 63r + -63r = 0 -63r + 28r3 = 0 Factor out the Greatest Common Factor (GCF), '7r'. 7r(-9 + 4r2) = 0 Factor a difference between two squares. 7r((3 + 2r)(-3 + 2r)) = 0 Ignore the factor 7.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 '(3 + 2r)' equal to zero and attempt to solve: Simplifying 3 + 2r = 0 Solving 3 + 2r = 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 + 2r = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 2r = 0 + -3 2r = 0 + -3 Combine like terms: 0 + -3 = -3 2r = -3 Divide each side by '2'. r = -1.5 Simplifying r = -1.5Subproblem 3
Set the factor '(-3 + 2r)' equal to zero and attempt to solve: Simplifying -3 + 2r = 0 Solving -3 + 2r = 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 + 2r = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2r = 0 + 3 2r = 0 + 3 Combine like terms: 0 + 3 = 3 2r = 3 Divide each side by '2'. r = 1.5 Simplifying r = 1.5Solution
r = {0, -1.5, 1.5}
