Factor a trinomial. (-9 + -2r)(5 + -1r) = 0Subproblem 1
Set the factor '(-9 + -2r)' equal to zero and attempt to solve: Simplifying -9 + -2r = 0 Solving -9 + -2r = 0 Move all terms containing r to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + -2r = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -2r = 0 + 9 -2r = 0 + 9 Combine like terms: 0 + 9 = 9 -2r = 9 Divide each side by '-2'. r = -4.5 Simplifying r = -4.5Subproblem 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 = {-4.5, 5}
