Simplifying 3n * 5 = 3 * 1 + -1n2 Reorder the terms for easier multiplication: 3 * 5n = 3 * 1 + -1n2 Multiply 3 * 5 15n = 3 * 1 + -1n2 Multiply 3 * 1 15n = 3 + -1n2 Solving 15n = 3 + -1n2 Solving for variable 'n'. Reorder the terms: -3 + 15n + n2 = 3 + -1n2 + -3 + n2 Reorder the terms: -3 + 15n + n2 = 3 + -3 + -1n2 + n2 Combine like terms: 3 + -3 = 0 -3 + 15n + n2 = 0 + -1n2 + n2 -3 + 15n + n2 = -1n2 + n2 Combine like terms: -1n2 + n2 = 0 -3 + 15n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '3' to each side of the equation. -3 + 15n + 3 + n2 = 0 + 3 Reorder the terms: -3 + 3 + 15n + n2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 15n + n2 = 0 + 3 15n + n2 = 0 + 3 Combine like terms: 0 + 3 = 3 15n + n2 = 3 The n term is 15n. Take half its coefficient (7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. 15n + 56.25 + n2 = 3 + 56.25 Reorder the terms: 56.25 + 15n + n2 = 3 + 56.25 Combine like terms: 3 + 56.25 = 59.25 56.25 + 15n + n2 = 59.25 Factor a perfect square on the left side: (n + 7.5)(n + 7.5) = 59.25 Calculate the square root of the right side: 7.697402159 Break this problem into two subproblems by setting (n + 7.5) equal to 7.697402159 and -7.697402159.Subproblem 1
n + 7.5 = 7.697402159 Simplifying n + 7.5 = 7.697402159 Reorder the terms: 7.5 + n = 7.697402159 Solving 7.5 + n = 7.697402159 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + n = 7.697402159 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + n = 7.697402159 + -7.5 n = 7.697402159 + -7.5 Combine like terms: 7.697402159 + -7.5 = 0.197402159 n = 0.197402159 Simplifying n = 0.197402159Subproblem 2
n + 7.5 = -7.697402159 Simplifying n + 7.5 = -7.697402159 Reorder the terms: 7.5 + n = -7.697402159 Solving 7.5 + n = -7.697402159 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + n = -7.697402159 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + n = -7.697402159 + -7.5 n = -7.697402159 + -7.5 Combine like terms: -7.697402159 + -7.5 = -15.197402159 n = -15.197402159 Simplifying n = -15.197402159Solution
The solution to the problem is based on the solutions from the subproblems. n = {0.197402159, -15.197402159}
