Simplifying r2(3r + 2)(3r + -2) = 0 Reorder the terms: r2(2 + 3r)(3r + -2) = 0 Reorder the terms: r2(2 + 3r)(-2 + 3r) = 0 Multiply (2 + 3r) * (-2 + 3r) r2(2(-2 + 3r) + 3r * (-2 + 3r)) = 0 r2((-2 * 2 + 3r * 2) + 3r * (-2 + 3r)) = 0 r2((-4 + 6r) + 3r * (-2 + 3r)) = 0 r2(-4 + 6r + (-2 * 3r + 3r * 3r)) = 0 r2(-4 + 6r + (-6r + 9r2)) = 0 Combine like terms: 6r + -6r = 0 r2(-4 + 0 + 9r2) = 0 r2(-4 + 9r2) = 0 (-4 * r2 + 9r2 * r2) = 0 (-4r2 + 9r4) = 0 Solving -4r2 + 9r4 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), 'r2'. r2(-4 + 9r2) = 0 Factor a difference between two squares. r2((2 + 3r)(-2 + 3r)) = 0Subproblem 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 '(2 + 3r)' equal to zero and attempt to solve: Simplifying 2 + 3r = 0 Solving 2 + 3r = 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 + 3r = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 3r = 0 + -2 3r = 0 + -2 Combine like terms: 0 + -2 = -2 3r = -2 Divide each side by '3'. r = -0.6666666667 Simplifying r = -0.6666666667Subproblem 3
Set the factor '(-2 + 3r)' equal to zero and attempt to solve: Simplifying -2 + 3r = 0 Solving -2 + 3r = 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 + 3r = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 3r = 0 + 2 3r = 0 + 2 Combine like terms: 0 + 2 = 2 3r = 2 Divide each side by '3'. r = 0.6666666667 Simplifying r = 0.6666666667Solution
r = {0, -0.6666666667, 0.6666666667}
