Simplifying 8n(4n + 7) = 25 Reorder the terms: 8n(7 + 4n) = 25 (7 * 8n + 4n * 8n) = 25 (56n + 32n2) = 25 Solving 56n + 32n2 = 25 Solving for variable 'n'. Reorder the terms: -25 + 56n + 32n2 = 25 + -25 Combine like terms: 25 + -25 = 0 -25 + 56n + 32n2 = 0 Begin completing the square. Divide all terms by 32 the coefficient of the squared term: Divide each side by '32'. -0.78125 + 1.75n + n2 = 0 Move the constant term to the right: Add '0.78125' to each side of the equation. -0.78125 + 1.75n + 0.78125 + n2 = 0 + 0.78125 Reorder the terms: -0.78125 + 0.78125 + 1.75n + n2 = 0 + 0.78125 Combine like terms: -0.78125 + 0.78125 = 0.00000 0.00000 + 1.75n + n2 = 0 + 0.78125 1.75n + n2 = 0 + 0.78125 Combine like terms: 0 + 0.78125 = 0.78125 1.75n + n2 = 0.78125 The n term is 1.75n. Take half its coefficient (0.875). Square it (0.765625) and add it to both sides. Add '0.765625' to each side of the equation. 1.75n + 0.765625 + n2 = 0.78125 + 0.765625 Reorder the terms: 0.765625 + 1.75n + n2 = 0.78125 + 0.765625 Combine like terms: 0.78125 + 0.765625 = 1.546875 0.765625 + 1.75n + n2 = 1.546875 Factor a perfect square on the left side: (n + 0.875)(n + 0.875) = 1.546875 Calculate the square root of the right side: 1.243734296 Break this problem into two subproblems by setting (n + 0.875) equal to 1.243734296 and -1.243734296.Subproblem 1
n + 0.875 = 1.243734296 Simplifying n + 0.875 = 1.243734296 Reorder the terms: 0.875 + n = 1.243734296 Solving 0.875 + n = 1.243734296 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.875' to each side of the equation. 0.875 + -0.875 + n = 1.243734296 + -0.875 Combine like terms: 0.875 + -0.875 = 0.000 0.000 + n = 1.243734296 + -0.875 n = 1.243734296 + -0.875 Combine like terms: 1.243734296 + -0.875 = 0.368734296 n = 0.368734296 Simplifying n = 0.368734296Subproblem 2
n + 0.875 = -1.243734296 Simplifying n + 0.875 = -1.243734296 Reorder the terms: 0.875 + n = -1.243734296 Solving 0.875 + n = -1.243734296 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.875' to each side of the equation. 0.875 + -0.875 + n = -1.243734296 + -0.875 Combine like terms: 0.875 + -0.875 = 0.000 0.000 + n = -1.243734296 + -0.875 n = -1.243734296 + -0.875 Combine like terms: -1.243734296 + -0.875 = -2.118734296 n = -2.118734296 Simplifying n = -2.118734296Solution
