Simplifying (6 + -2n) * 8n = 34 Reorder the terms for easier multiplication: 8n(6 + -2n) = 34 (6 * 8n + -2n * 8n) = 34 (48n + -16n2) = 34 Solving 48n + -16n2 = 34 Solving for variable 'n'. Reorder the terms: -34 + 48n + -16n2 = 34 + -34 Combine like terms: 34 + -34 = 0 -34 + 48n + -16n2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-17 + 24n + -8n2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-17 + 24n + -8n2)' equal to zero and attempt to solve: Simplifying -17 + 24n + -8n2 = 0 Solving -17 + 24n + -8n2 = 0 Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. 2.125 + -3n + n2 = 0 Move the constant term to the right: Add '-2.125' to each side of the equation. 2.125 + -3n + -2.125 + n2 = 0 + -2.125 Reorder the terms: 2.125 + -2.125 + -3n + n2 = 0 + -2.125 Combine like terms: 2.125 + -2.125 = 0.000 0.000 + -3n + n2 = 0 + -2.125 -3n + n2 = 0 + -2.125 Combine like terms: 0 + -2.125 = -2.125 -3n + n2 = -2.125 The n term is -3n. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3n + 2.25 + n2 = -2.125 + 2.25 Reorder the terms: 2.25 + -3n + n2 = -2.125 + 2.25 Combine like terms: -2.125 + 2.25 = 0.125 2.25 + -3n + n2 = 0.125 Factor a perfect square on the left side: (n + -1.5)(n + -1.5) = 0.125 Calculate the square root of the right side: 0.353553391 Break this problem into two subproblems by setting (n + -1.5) equal to 0.353553391 and -0.353553391.Subproblem 1
n + -1.5 = 0.353553391 Simplifying n + -1.5 = 0.353553391 Reorder the terms: -1.5 + n = 0.353553391 Solving -1.5 + n = 0.353553391 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + n = 0.353553391 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + n = 0.353553391 + 1.5 n = 0.353553391 + 1.5 Combine like terms: 0.353553391 + 1.5 = 1.853553391 n = 1.853553391 Simplifying n = 1.853553391Subproblem 2
n + -1.5 = -0.353553391 Simplifying n + -1.5 = -0.353553391 Reorder the terms: -1.5 + n = -0.353553391 Solving -1.5 + n = -0.353553391 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + n = -0.353553391 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + n = -0.353553391 + 1.5 n = -0.353553391 + 1.5 Combine like terms: -0.353553391 + 1.5 = 1.146446609 n = 1.146446609 Simplifying n = 1.146446609Solution
