Simplifying 8n(5n + 6) = 15 Reorder the terms: 8n(6 + 5n) = 15 (6 * 8n + 5n * 8n) = 15 (48n + 40n2) = 15 Solving 48n + 40n2 = 15 Solving for variable 'n'. Reorder the terms: -15 + 48n + 40n2 = 15 + -15 Combine like terms: 15 + -15 = 0 -15 + 48n + 40n2 = 0 Begin completing the square. Divide all terms by 40 the coefficient of the squared term: Divide each side by '40'. -0.375 + 1.2n + n2 = 0.0 Move the constant term to the right: Add '0.375' to each side of the equation. -0.375 + 1.2n + 0.375 + n2 = 0.0 + 0.375 Reorder the terms: -0.375 + 0.375 + 1.2n + n2 = 0.0 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + 1.2n + n2 = 0.0 + 0.375 1.2n + n2 = 0.0 + 0.375 Combine like terms: 0.0 + 0.375 = 0.375 1.2n + n2 = 0.375 The n term is 1.2n. Take half its coefficient (0.6). Square it (0.36) and add it to both sides. Add '0.36' to each side of the equation. 1.2n + 0.36 + n2 = 0.375 + 0.36 Reorder the terms: 0.36 + 1.2n + n2 = 0.375 + 0.36 Combine like terms: 0.375 + 0.36 = 0.735 0.36 + 1.2n + n2 = 0.735 Factor a perfect square on the left side: (n + 0.6)(n + 0.6) = 0.735 Calculate the square root of the right side: 0.85732141 Break this problem into two subproblems by setting (n + 0.6) equal to 0.85732141 and -0.85732141.Subproblem 1
n + 0.6 = 0.85732141 Simplifying n + 0.6 = 0.85732141 Reorder the terms: 0.6 + n = 0.85732141 Solving 0.6 + n = 0.85732141 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.6' to each side of the equation. 0.6 + -0.6 + n = 0.85732141 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 0.0 + n = 0.85732141 + -0.6 n = 0.85732141 + -0.6 Combine like terms: 0.85732141 + -0.6 = 0.25732141 n = 0.25732141 Simplifying n = 0.25732141Subproblem 2
n + 0.6 = -0.85732141 Simplifying n + 0.6 = -0.85732141 Reorder the terms: 0.6 + n = -0.85732141 Solving 0.6 + n = -0.85732141 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.6' to each side of the equation. 0.6 + -0.6 + n = -0.85732141 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 0.0 + n = -0.85732141 + -0.6 n = -0.85732141 + -0.6 Combine like terms: -0.85732141 + -0.6 = -1.45732141 n = -1.45732141 Simplifying n = -1.45732141Solution
The solution to the problem is based on the solutions from the subproblems. n = {0.25732141, -1.45732141}
