Simplifying 5n2 + n = 9 Reorder the terms: n + 5n2 = 9 Solving n + 5n2 = 9 Solving for variable 'n'. Reorder the terms: -9 + n + 5n2 = 9 + -9 Combine like terms: 9 + -9 = 0 -9 + n + 5n2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1.8 + 0.2n + n2 = 0 Move the constant term to the right: Add '1.8' to each side of the equation. -1.8 + 0.2n + 1.8 + n2 = 0 + 1.8 Reorder the terms: -1.8 + 1.8 + 0.2n + n2 = 0 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + 0.2n + n2 = 0 + 1.8 0.2n + n2 = 0 + 1.8 Combine like terms: 0 + 1.8 = 1.8 0.2n + n2 = 1.8 The n term is n. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.2n + 0.25 + n2 = 1.8 + 0.25 Reorder the terms: 0.25 + 0.2n + n2 = 1.8 + 0.25 Combine like terms: 1.8 + 0.25 = 2.05 0.25 + 0.2n + n2 = 2.05 Factor a perfect square on the left side: (n + 0.5)(n + 0.5) = 2.05 Calculate the square root of the right side: 1.431782106 Break this problem into two subproblems by setting (n + 0.5) equal to 1.431782106 and -1.431782106.Subproblem 1
n + 0.5 = 1.431782106 Simplifying n + 0.5 = 1.431782106 Reorder the terms: 0.5 + n = 1.431782106 Solving 0.5 + n = 1.431782106 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + n = 1.431782106 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + n = 1.431782106 + -0.5 n = 1.431782106 + -0.5 Combine like terms: 1.431782106 + -0.5 = 0.931782106 n = 0.931782106 Simplifying n = 0.931782106Subproblem 2
n + 0.5 = -1.431782106 Simplifying n + 0.5 = -1.431782106 Reorder the terms: 0.5 + n = -1.431782106 Solving 0.5 + n = -1.431782106 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + n = -1.431782106 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + n = -1.431782106 + -0.5 n = -1.431782106 + -0.5 Combine like terms: -1.431782106 + -0.5 = -1.931782106 n = -1.931782106 Simplifying n = -1.931782106Solution
The solution to the problem is based on the solutions from the subproblems. n = {0.931782106, -1.931782106}
