Simplifying 3n2 + 60 = -27n Reorder the terms: 60 + 3n2 = -27n Solving 60 + 3n2 = -27n Solving for variable 'n'. Reorder the terms: 60 + 27n + 3n2 = -27n + 27n Combine like terms: -27n + 27n = 0 60 + 27n + 3n2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(20 + 9n + n2) = 0 Factor a trinomial. 3((5 + n)(4 + n)) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(5 + n)' equal to zero and attempt to solve: Simplifying 5 + n = 0 Solving 5 + n = 0 Move all terms containing n to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + n = 0 + -5 Combine like terms: 5 + -5 = 0 0 + n = 0 + -5 n = 0 + -5 Combine like terms: 0 + -5 = -5 n = -5 Simplifying n = -5Subproblem 2
Set the factor '(4 + n)' equal to zero and attempt to solve: Simplifying 4 + n = 0 Solving 4 + n = 0 Move all terms containing n to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + n = 0 + -4 Combine like terms: 4 + -4 = 0 0 + n = 0 + -4 n = 0 + -4 Combine like terms: 0 + -4 = -4 n = -4 Simplifying n = -4Solution
n = {-5, -4}
