Simplifying 7 + 2[n + -5] * n = 3.6 Reorder the terms: 7 + 2[-5 + n] * n = 3.6 Reorder the terms for easier multiplication: 7 + 2n[-5 + n] = 3.6 7 + [-5 * 2n + n * 2n] = 3.6 7 + [-10n + 2n2] = 3.6 Solving 7 + -10n + 2n2 = 3.6 Solving for variable 'n'. Reorder the terms: 7 + -3.6 + -10n + 2n2 = 3.6 + -3.6 Combine like terms: 7 + -3.6 = 3.4 3.4 + -10n + 2n2 = 3.6 + -3.6 Combine like terms: 3.6 + -3.6 = 0.0 3.4 + -10n + 2n2 = 0.0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 1.7 + -5n + n2 = 0.0 Move the constant term to the right: Add '-1.7' to each side of the equation. 1.7 + -5n + -1.7 + n2 = 0.0 + -1.7 Reorder the terms: 1.7 + -1.7 + -5n + n2 = 0.0 + -1.7 Combine like terms: 1.7 + -1.7 = 0.0 0.0 + -5n + n2 = 0.0 + -1.7 -5n + n2 = 0.0 + -1.7 Combine like terms: 0.0 + -1.7 = -1.7 -5n + n2 = -1.7 The n term is -5n. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5n + 6.25 + n2 = -1.7 + 6.25 Reorder the terms: 6.25 + -5n + n2 = -1.7 + 6.25 Combine like terms: -1.7 + 6.25 = 4.55 6.25 + -5n + n2 = 4.55 Factor a perfect square on the left side: (n + -2.5)(n + -2.5) = 4.55 Calculate the square root of the right side: 2.133072901 Break this problem into two subproblems by setting (n + -2.5) equal to 2.133072901 and -2.133072901.Subproblem 1
n + -2.5 = 2.133072901 Simplifying n + -2.5 = 2.133072901 Reorder the terms: -2.5 + n = 2.133072901 Solving -2.5 + n = 2.133072901 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + n = 2.133072901 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + n = 2.133072901 + 2.5 n = 2.133072901 + 2.5 Combine like terms: 2.133072901 + 2.5 = 4.633072901 n = 4.633072901 Simplifying n = 4.633072901Subproblem 2
n + -2.5 = -2.133072901 Simplifying n + -2.5 = -2.133072901 Reorder the terms: -2.5 + n = -2.133072901 Solving -2.5 + n = -2.133072901 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + n = -2.133072901 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + n = -2.133072901 + 2.5 n = -2.133072901 + 2.5 Combine like terms: -2.133072901 + 2.5 = 0.366927099 n = 0.366927099 Simplifying n = 0.366927099Solution
The solution to the problem is based on the solutions from the subproblems. n = {4.633072901, 0.366927099}
