Simplifying -1r2 + -41r + -40 = 0 Reorder the terms: -40 + -41r + -1r2 = 0 Solving -40 + -41r + -1r2 = 0 Solving for variable 'r'. Factor out the Greatest Common Factor (GCF), '-1'. -1(40 + 41r + r2) = 0 Factor a trinomial. -1((40 + r)(1 + r)) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(40 + r)' equal to zero and attempt to solve: Simplifying 40 + r = 0 Solving 40 + r = 0 Move all terms containing r to the left, all other terms to the right. Add '-40' to each side of the equation. 40 + -40 + r = 0 + -40 Combine like terms: 40 + -40 = 0 0 + r = 0 + -40 r = 0 + -40 Combine like terms: 0 + -40 = -40 r = -40 Simplifying r = -40Subproblem 2
Set the factor '(1 + r)' equal to zero and attempt to solve: Simplifying 1 + r = 0 Solving 1 + r = 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 + r = 0 + -1 Combine like terms: 1 + -1 = 0 0 + r = 0 + -1 r = 0 + -1 Combine like terms: 0 + -1 = -1 r = -1 Simplifying r = -1Solution
r = {-40, -1}
