Simplifying n2 = -18 + -10n Solving n2 = -18 + -10n Solving for variable 'n'. Reorder the terms: 18 + 10n + n2 = -18 + -10n + 18 + 10n Reorder the terms: 18 + 10n + n2 = -18 + 18 + -10n + 10n Combine like terms: -18 + 18 = 0 18 + 10n + n2 = 0 + -10n + 10n 18 + 10n + n2 = -10n + 10n Combine like terms: -10n + 10n = 0 18 + 10n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + 10n + -18 + n2 = 0 + -18 Reorder the terms: 18 + -18 + 10n + n2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + 10n + n2 = 0 + -18 10n + n2 = 0 + -18 Combine like terms: 0 + -18 = -18 10n + n2 = -18 The n term is 10n. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10n + 25 + n2 = -18 + 25 Reorder the terms: 25 + 10n + n2 = -18 + 25 Combine like terms: -18 + 25 = 7 25 + 10n + n2 = 7 Factor a perfect square on the left side: (n + 5)(n + 5) = 7 Calculate the square root of the right side: 2.645751311 Break this problem into two subproblems by setting (n + 5) equal to 2.645751311 and -2.645751311.Subproblem 1
n + 5 = 2.645751311 Simplifying n + 5 = 2.645751311 Reorder the terms: 5 + n = 2.645751311 Solving 5 + n = 2.645751311 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + n = 2.645751311 + -5 Combine like terms: 5 + -5 = 0 0 + n = 2.645751311 + -5 n = 2.645751311 + -5 Combine like terms: 2.645751311 + -5 = -2.354248689 n = -2.354248689 Simplifying n = -2.354248689Subproblem 2
