Simplifying 8n2 = 38n + -10 Reorder the terms: 8n2 = -10 + 38n Solving 8n2 = -10 + 38n Solving for variable 'n'. Reorder the terms: 10 + -38n + 8n2 = -10 + 38n + 10 + -38n Reorder the terms: 10 + -38n + 8n2 = -10 + 10 + 38n + -38n Combine like terms: -10 + 10 = 0 10 + -38n + 8n2 = 0 + 38n + -38n 10 + -38n + 8n2 = 38n + -38n Combine like terms: 38n + -38n = 0 10 + -38n + 8n2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(5 + -19n + 4n2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(5 + -19n + 4n2)' equal to zero and attempt to solve: Simplifying 5 + -19n + 4n2 = 0 Solving 5 + -19n + 4n2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.25 + -4.75n + n2 = 0 Move the constant term to the right: Add '-1.25' to each side of the equation. 1.25 + -4.75n + -1.25 + n2 = 0 + -1.25 Reorder the terms: 1.25 + -1.25 + -4.75n + n2 = 0 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + -4.75n + n2 = 0 + -1.25 -4.75n + n2 = 0 + -1.25 Combine like terms: 0 + -1.25 = -1.25 -4.75n + n2 = -1.25 The n term is -4.75n. Take half its coefficient (-2.375). Square it (5.640625) and add it to both sides. Add '5.640625' to each side of the equation. -4.75n + 5.640625 + n2 = -1.25 + 5.640625 Reorder the terms: 5.640625 + -4.75n + n2 = -1.25 + 5.640625 Combine like terms: -1.25 + 5.640625 = 4.390625 5.640625 + -4.75n + n2 = 4.390625 Factor a perfect square on the left side: (n + -2.375)(n + -2.375) = 4.390625 Calculate the square root of the right side: 2.095381827 Break this problem into two subproblems by setting (n + -2.375) equal to 2.095381827 and -2.095381827.Subproblem 1
n + -2.375 = 2.095381827 Simplifying n + -2.375 = 2.095381827 Reorder the terms: -2.375 + n = 2.095381827 Solving -2.375 + n = 2.095381827 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '2.375' to each side of the equation. -2.375 + 2.375 + n = 2.095381827 + 2.375 Combine like terms: -2.375 + 2.375 = 0.000 0.000 + n = 2.095381827 + 2.375 n = 2.095381827 + 2.375 Combine like terms: 2.095381827 + 2.375 = 4.470381827 n = 4.470381827 Simplifying n = 4.470381827Subproblem 2
n + -2.375 = -2.095381827 Simplifying n + -2.375 = -2.095381827 Reorder the terms: -2.375 + n = -2.095381827 Solving -2.375 + n = -2.095381827 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '2.375' to each side of the equation. -2.375 + 2.375 + n = -2.095381827 + 2.375 Combine like terms: -2.375 + 2.375 = 0.000 0.000 + n = -2.095381827 + 2.375 n = -2.095381827 + 2.375 Combine like terms: -2.095381827 + 2.375 = 0.279618173 n = 0.279618173 Simplifying n = 0.279618173Solution
