Simplifying n2 + 18n + 15 = 0 Reorder the terms: 15 + 18n + n2 = 0 Solving 15 + 18n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '-15' to each side of the equation. 15 + 18n + -15 + n2 = 0 + -15 Reorder the terms: 15 + -15 + 18n + n2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + 18n + n2 = 0 + -15 18n + n2 = 0 + -15 Combine like terms: 0 + -15 = -15 18n + n2 = -15 The n term is 18n. Take half its coefficient (9). Square it (81) and add it to both sides. Add '81' to each side of the equation. 18n + 81 + n2 = -15 + 81 Reorder the terms: 81 + 18n + n2 = -15 + 81 Combine like terms: -15 + 81 = 66 81 + 18n + n2 = 66 Factor a perfect square on the left side: (n + 9)(n + 9) = 66 Calculate the square root of the right side: 8.124038405 Break this problem into two subproblems by setting (n + 9) equal to 8.124038405 and -8.124038405.Subproblem 1
n + 9 = 8.124038405 Simplifying n + 9 = 8.124038405 Reorder the terms: 9 + n = 8.124038405 Solving 9 + n = 8.124038405 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + n = 8.124038405 + -9 Combine like terms: 9 + -9 = 0 0 + n = 8.124038405 + -9 n = 8.124038405 + -9 Combine like terms: 8.124038405 + -9 = -0.875961595 n = -0.875961595 Simplifying n = -0.875961595Subproblem 2
n + 9 = -8.124038405 Simplifying n + 9 = -8.124038405 Reorder the terms: 9 + n = -8.124038405 Solving 9 + n = -8.124038405 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + n = -8.124038405 + -9 Combine like terms: 9 + -9 = 0 0 + n = -8.124038405 + -9 n = -8.124038405 + -9 Combine like terms: -8.124038405 + -9 = -17.124038405 n = -17.124038405 Simplifying n = -17.124038405Solution
The solution to the problem is based on the solutions from the subproblems. n = {-0.875961595, -17.124038405}
