Simplifying n2 + n + -338 = 0 Reorder the terms: -338 + n + n2 = 0 Solving -338 + n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '338' to each side of the equation. -338 + n + 338 + n2 = 0 + 338 Reorder the terms: -338 + 338 + n + n2 = 0 + 338 Combine like terms: -338 + 338 = 0 0 + n + n2 = 0 + 338 n + n2 = 0 + 338 Combine like terms: 0 + 338 = 338 n + n2 = 338 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. n + 0.25 + n2 = 338 + 0.25 Reorder the terms: 0.25 + n + n2 = 338 + 0.25 Combine like terms: 338 + 0.25 = 338.25 0.25 + n + n2 = 338.25 Factor a perfect square on the left side: (n + 0.5)(n + 0.5) = 338.25 Calculate the square root of the right side: 18.391574158 Break this problem into two subproblems by setting (n + 0.5) equal to 18.391574158 and -18.391574158.Subproblem 1
n + 0.5 = 18.391574158 Simplifying n + 0.5 = 18.391574158 Reorder the terms: 0.5 + n = 18.391574158 Solving 0.5 + n = 18.391574158 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 = 18.391574158 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + n = 18.391574158 + -0.5 n = 18.391574158 + -0.5 Combine like terms: 18.391574158 + -0.5 = 17.891574158 n = 17.891574158 Simplifying n = 17.891574158Subproblem 2
n + 0.5 = -18.391574158 Simplifying n + 0.5 = -18.391574158 Reorder the terms: 0.5 + n = -18.391574158 Solving 0.5 + n = -18.391574158 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 = -18.391574158 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + n = -18.391574158 + -0.5 n = -18.391574158 + -0.5 Combine like terms: -18.391574158 + -0.5 = -18.891574158 n = -18.891574158 Simplifying n = -18.891574158Solution
The solution to the problem is based on the solutions from the subproblems. n = {17.891574158, -18.891574158}
