Simplifying (r + 6)(r + 3) = -2 Reorder the terms: (6 + r)(r + 3) = -2 Reorder the terms: (6 + r)(3 + r) = -2 Multiply (6 + r) * (3 + r) (6(3 + r) + r(3 + r)) = -2 ((3 * 6 + r * 6) + r(3 + r)) = -2 ((18 + 6r) + r(3 + r)) = -2 (18 + 6r + (3 * r + r * r)) = -2 (18 + 6r + (3r + r2)) = -2 Combine like terms: 6r + 3r = 9r (18 + 9r + r2) = -2 Solving 18 + 9r + r2 = -2 Solving for variable 'r'. Reorder the terms: 18 + 2 + 9r + r2 = -2 + 2 Combine like terms: 18 + 2 = 20 20 + 9r + r2 = -2 + 2 Combine like terms: -2 + 2 = 0 20 + 9r + r2 = 0 Factor a trinomial. (5 + r)(4 + r) = 0Subproblem 1
Set the factor '(5 + r)' equal to zero and attempt to solve: Simplifying 5 + r = 0 Solving 5 + r = 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 + r = 0 + -5 Combine like terms: 5 + -5 = 0 0 + r = 0 + -5 r = 0 + -5 Combine like terms: 0 + -5 = -5 r = -5 Simplifying r = -5Subproblem 2
Set the factor '(4 + r)' equal to zero and attempt to solve: Simplifying 4 + r = 0 Solving 4 + r = 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 + r = 0 + -4 Combine like terms: 4 + -4 = 0 0 + r = 0 + -4 r = 0 + -4 Combine like terms: 0 + -4 = -4 r = -4 Simplifying r = -4Solution
r = {-5, -4}
