Simplifying 6r2 + -26r + -18 = 2 Reorder the terms: -18 + -26r + 6r2 = 2 Solving -18 + -26r + 6r2 = 2 Solving for variable 'r'. Reorder the terms: -18 + -2 + -26r + 6r2 = 2 + -2 Combine like terms: -18 + -2 = -20 -20 + -26r + 6r2 = 2 + -2 Combine like terms: 2 + -2 = 0 -20 + -26r + 6r2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-10 + -13r + 3r2) = 0 Factor a trinomial. 2((-2 + -3r)(5 + -1r)) = 0 Ignore the factor 2.Subproblem 1
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 2
Set the factor '(5 + -1r)' equal to zero and attempt to solve: Simplifying 5 + -1r = 0 Solving 5 + -1r = 0 Move all terms containing r to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -1r = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -1r = 0 + -5 -1r = 0 + -5 Combine like terms: 0 + -5 = -5 -1r = -5 Divide each side by '-1'. r = 5 Simplifying r = 5Solution
r = {-0.6666666667, 5}
