Simplifying 2n2 + 88n + -2730 = 0 Reorder the terms: -2730 + 88n + 2n2 = 0 Solving -2730 + 88n + 2n2 = 0 Solving for variable 'n'. Factor out the Greatest Common Factor (GCF), '2'. 2(-1365 + 44n + n2) = 0 Factor a trinomial. 2((-65 + -1n)(21 + -1n)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-65 + -1n)' equal to zero and attempt to solve: Simplifying -65 + -1n = 0 Solving -65 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '65' to each side of the equation. -65 + 65 + -1n = 0 + 65 Combine like terms: -65 + 65 = 0 0 + -1n = 0 + 65 -1n = 0 + 65 Combine like terms: 0 + 65 = 65 -1n = 65 Divide each side by '-1'. n = -65 Simplifying n = -65Subproblem 2
Set the factor '(21 + -1n)' equal to zero and attempt to solve: Simplifying 21 + -1n = 0 Solving 21 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '-21' to each side of the equation. 21 + -21 + -1n = 0 + -21 Combine like terms: 21 + -21 = 0 0 + -1n = 0 + -21 -1n = 0 + -21 Combine like terms: 0 + -21 = -21 -1n = -21 Divide each side by '-1'. n = 21 Simplifying n = 21Solution
n = {-65, 21}
