Simplifying n(n + 5) = 414 Reorder the terms: n(5 + n) = 414 (5 * n + n * n) = 414 (5n + n2) = 414 Solving 5n + n2 = 414 Solving for variable 'n'. Reorder the terms: -414 + 5n + n2 = 414 + -414 Combine like terms: 414 + -414 = 0 -414 + 5n + n2 = 0 Factor a trinomial. (-23 + -1n)(18 + -1n) = 0Subproblem 1
Set the factor '(-23 + -1n)' equal to zero and attempt to solve: Simplifying -23 + -1n = 0 Solving -23 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '23' to each side of the equation. -23 + 23 + -1n = 0 + 23 Combine like terms: -23 + 23 = 0 0 + -1n = 0 + 23 -1n = 0 + 23 Combine like terms: 0 + 23 = 23 -1n = 23 Divide each side by '-1'. n = -23 Simplifying n = -23Subproblem 2
Set the factor '(18 + -1n)' equal to zero and attempt to solve: Simplifying 18 + -1n = 0 Solving 18 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '-18' to each side of the equation. 18 + -18 + -1n = 0 + -18 Combine like terms: 18 + -18 = 0 0 + -1n = 0 + -18 -1n = 0 + -18 Combine like terms: 0 + -18 = -18 -1n = -18 Divide each side by '-1'. n = 18 Simplifying n = 18Solution
n = {-23, 18}
