Simplifying n(n + -1) = 4n + 18 Reorder the terms: n(-1 + n) = 4n + 18 (-1 * n + n * n) = 4n + 18 (-1n + n2) = 4n + 18 Reorder the terms: -1n + n2 = 18 + 4n Solving -1n + n2 = 18 + 4n Solving for variable 'n'. Reorder the terms: -18 + -1n + -4n + n2 = 18 + 4n + -18 + -4n Combine like terms: -1n + -4n = -5n -18 + -5n + n2 = 18 + 4n + -18 + -4n Reorder the terms: -18 + -5n + n2 = 18 + -18 + 4n + -4n Combine like terms: 18 + -18 = 0 -18 + -5n + n2 = 0 + 4n + -4n -18 + -5n + n2 = 4n + -4n Combine like terms: 4n + -4n = 0 -18 + -5n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '18' to each side of the equation. -18 + -5n + 18 + n2 = 0 + 18 Reorder the terms: -18 + 18 + -5n + n2 = 0 + 18 Combine like terms: -18 + 18 = 0 0 + -5n + n2 = 0 + 18 -5n + n2 = 0 + 18 Combine like terms: 0 + 18 = 18 -5n + n2 = 18 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 = 18 + 6.25 Reorder the terms: 6.25 + -5n + n2 = 18 + 6.25 Combine like terms: 18 + 6.25 = 24.25 6.25 + -5n + n2 = 24.25 Factor a perfect square on the left side: (n + -2.5)(n + -2.5) = 24.25 Calculate the square root of the right side: 4.924428901 Break this problem into two subproblems by setting (n + -2.5) equal to 4.924428901 and -4.924428901.Subproblem 1
n + -2.5 = 4.924428901 Simplifying n + -2.5 = 4.924428901 Reorder the terms: -2.5 + n = 4.924428901 Solving -2.5 + n = 4.924428901 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 = 4.924428901 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + n = 4.924428901 + 2.5 n = 4.924428901 + 2.5 Combine like terms: 4.924428901 + 2.5 = 7.424428901 n = 7.424428901 Simplifying n = 7.424428901Subproblem 2
n + -2.5 = -4.924428901 Simplifying n + -2.5 = -4.924428901 Reorder the terms: -2.5 + n = -4.924428901 Solving -2.5 + n = -4.924428901 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 = -4.924428901 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + n = -4.924428901 + 2.5 n = -4.924428901 + 2.5 Combine like terms: -4.924428901 + 2.5 = -2.424428901 n = -2.424428901 Simplifying n = -2.424428901Solution
The solution to the problem is based on the solutions from the subproblems. n = {7.424428901, -2.424428901}
