Simplifying n2 = 3n + 9 Reorder the terms: n2 = 9 + 3n Solving n2 = 9 + 3n Solving for variable 'n'. Reorder the terms: -9 + -3n + n2 = 9 + 3n + -9 + -3n Reorder the terms: -9 + -3n + n2 = 9 + -9 + 3n + -3n Combine like terms: 9 + -9 = 0 -9 + -3n + n2 = 0 + 3n + -3n -9 + -3n + n2 = 3n + -3n Combine like terms: 3n + -3n = 0 -9 + -3n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '9' to each side of the equation. -9 + -3n + 9 + n2 = 0 + 9 Reorder the terms: -9 + 9 + -3n + n2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -3n + n2 = 0 + 9 -3n + n2 = 0 + 9 Combine like terms: 0 + 9 = 9 -3n + n2 = 9 The n term is -3n. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3n + 2.25 + n2 = 9 + 2.25 Reorder the terms: 2.25 + -3n + n2 = 9 + 2.25 Combine like terms: 9 + 2.25 = 11.25 2.25 + -3n + n2 = 11.25 Factor a perfect square on the left side: (n + -1.5)(n + -1.5) = 11.25 Calculate the square root of the right side: 3.354101966 Break this problem into two subproblems by setting (n + -1.5) equal to 3.354101966 and -3.354101966.Subproblem 1
n + -1.5 = 3.354101966 Simplifying n + -1.5 = 3.354101966 Reorder the terms: -1.5 + n = 3.354101966 Solving -1.5 + n = 3.354101966 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + n = 3.354101966 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + n = 3.354101966 + 1.5 n = 3.354101966 + 1.5 Combine like terms: 3.354101966 + 1.5 = 4.854101966 n = 4.854101966 Simplifying n = 4.854101966Subproblem 2
n + -1.5 = -3.354101966 Simplifying n + -1.5 = -3.354101966 Reorder the terms: -1.5 + n = -3.354101966 Solving -1.5 + n = -3.354101966 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + n = -3.354101966 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + n = -3.354101966 + 1.5 n = -3.354101966 + 1.5 Combine like terms: -3.354101966 + 1.5 = -1.854101966 n = -1.854101966 Simplifying n = -1.854101966Solution
The solution to the problem is based on the solutions from the subproblems. n = {4.854101966, -1.854101966}
