Simplifying n(n + 2) = 12.5316 Reorder the terms: n(2 + n) = 12.5316 (2 * n + n * n) = 12.5316 (2n + n2) = 12.5316 Solving 2n + n2 = 12.5316 Solving for variable 'n'. Reorder the terms: -12.5316 + 2n + n2 = 12.5316 + -12.5316 Combine like terms: 12.5316 + -12.5316 = 0.0000 -12.5316 + 2n + n2 = 0.0000 Begin completing the square. Move the constant term to the right: Add '12.5316' to each side of the equation. -12.5316 + 2n + 12.5316 + n2 = 0.0000 + 12.5316 Reorder the terms: -12.5316 + 12.5316 + 2n + n2 = 0.0000 + 12.5316 Combine like terms: -12.5316 + 12.5316 = 0.0000 0.0000 + 2n + n2 = 0.0000 + 12.5316 2n + n2 = 0.0000 + 12.5316 Combine like terms: 0.0000 + 12.5316 = 12.5316 2n + n2 = 12.5316 The n term is 2n. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2n + 1 + n2 = 12.5316 + 1 Reorder the terms: 1 + 2n + n2 = 12.5316 + 1 Combine like terms: 12.5316 + 1 = 13.5316 1 + 2n + n2 = 13.5316 Factor a perfect square on the left side: (n + 1)(n + 1) = 13.5316 Calculate the square root of the right side: 3.678532316 Break this problem into two subproblems by setting (n + 1) equal to 3.678532316 and -3.678532316.Subproblem 1
n + 1 = 3.678532316 Simplifying n + 1 = 3.678532316 Reorder the terms: 1 + n = 3.678532316 Solving 1 + n = 3.678532316 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + n = 3.678532316 + -1 Combine like terms: 1 + -1 = 0 0 + n = 3.678532316 + -1 n = 3.678532316 + -1 Combine like terms: 3.678532316 + -1 = 2.678532316 n = 2.678532316 Simplifying n = 2.678532316Subproblem 2
n + 1 = -3.678532316 Simplifying n + 1 = -3.678532316 Reorder the terms: 1 + n = -3.678532316 Solving 1 + n = -3.678532316 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + n = -3.678532316 + -1 Combine like terms: 1 + -1 = 0 0 + n = -3.678532316 + -1 n = -3.678532316 + -1 Combine like terms: -3.678532316 + -1 = -4.678532316 n = -4.678532316 Simplifying n = -4.678532316Solution
