Simplifying (4r + 2)(5r + -4) = 0 Reorder the terms: (2 + 4r)(5r + -4) = 0 Reorder the terms: (2 + 4r)(-4 + 5r) = 0 Multiply (2 + 4r) * (-4 + 5r) (2(-4 + 5r) + 4r * (-4 + 5r)) = 0 ((-4 * 2 + 5r * 2) + 4r * (-4 + 5r)) = 0 ((-8 + 10r) + 4r * (-4 + 5r)) = 0 (-8 + 10r + (-4 * 4r + 5r * 4r)) = 0 (-8 + 10r + (-16r + 20r2)) = 0 Combine like terms: 10r + -16r = -6r (-8 + -6r + 20r2) = 0 Solving -8 + -6r + 20r2 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), '2'. 2(-4 + -3r + 10r2) = 0 Factor a trinomial. 2((-1 + -2r)(4 + -5r)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-1 + -2r)' equal to zero and attempt to solve: Simplifying -1 + -2r = 0 Solving -1 + -2r = 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 + -2r = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -2r = 0 + 1 -2r = 0 + 1 Combine like terms: 0 + 1 = 1 -2r = 1 Divide each side by '-2'. r = -0.5 Simplifying r = -0.5Subproblem 2
Set the factor '(4 + -5r)' equal to zero and attempt to solve: Simplifying 4 + -5r = 0 Solving 4 + -5r = 0 Move all terms containing r to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -5r = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -5r = 0 + -4 -5r = 0 + -4 Combine like terms: 0 + -4 = -4 -5r = -4 Divide each side by '-5'. r = 0.8 Simplifying r = 0.8Solution
r = {-0.5, 0.8}
