Simplifying 6r2 + -3r = 3 Reorder the terms: -3r + 6r2 = 3 Solving -3r + 6r2 = 3 Solving for variable 'r'. Reorder the terms: -3 + -3r + 6r2 = 3 + -3 Combine like terms: 3 + -3 = 0 -3 + -3r + 6r2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(-1 + -1r + 2r2) = 0 Factor a trinomial. 3((-1 + -2r)(1 + -1r)) = 0 Ignore the factor 3.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 '(1 + -1r)' equal to zero and attempt to solve: Simplifying 1 + -1r = 0 Solving 1 + -1r = 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 + -1r = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1r = 0 + -1 -1r = 0 + -1 Combine like terms: 0 + -1 = -1 -1r = -1 Divide each side by '-1'. r = 1 Simplifying r = 1Solution
r = {-0.5, 1}
