Simplifying n(n + -2) = 4 Reorder the terms: n(-2 + n) = 4 (-2 * n + n * n) = 4 (-2n + n2) = 4 Solving -2n + n2 = 4 Solving for variable 'n'. Reorder the terms: -4 + -2n + n2 = 4 + -4 Combine like terms: 4 + -4 = 0 -4 + -2n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '4' to each side of the equation. -4 + -2n + 4 + n2 = 0 + 4 Reorder the terms: -4 + 4 + -2n + n2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -2n + n2 = 0 + 4 -2n + n2 = 0 + 4 Combine like terms: 0 + 4 = 4 -2n + n2 = 4 The n term is -2n. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2n + 1 + n2 = 4 + 1 Reorder the terms: 1 + -2n + n2 = 4 + 1 Combine like terms: 4 + 1 = 5 1 + -2n + n2 = 5 Factor a perfect square on the left side: (n + -1)(n + -1) = 5 Calculate the square root of the right side: 2.236067978 Break this problem into two subproblems by setting (n + -1) equal to 2.236067978 and -2.236067978.Subproblem 1
n + -1 = 2.236067978 Simplifying n + -1 = 2.236067978 Reorder the terms: -1 + n = 2.236067978 Solving -1 + n = 2.236067978 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + n = 2.236067978 + 1 Combine like terms: -1 + 1 = 0 0 + n = 2.236067978 + 1 n = 2.236067978 + 1 Combine like terms: 2.236067978 + 1 = 3.236067978 n = 3.236067978 Simplifying n = 3.236067978Subproblem 2
n + -1 = -2.236067978 Simplifying n + -1 = -2.236067978 Reorder the terms: -1 + n = -2.236067978 Solving -1 + n = -2.236067978 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + n = -2.236067978 + 1 Combine like terms: -1 + 1 = 0 0 + n = -2.236067978 + 1 n = -2.236067978 + 1 Combine like terms: -2.236067978 + 1 = -1.236067978 n = -1.236067978 Simplifying n = -1.236067978Solution
The solution to the problem is based on the solutions from the subproblems. n = {3.236067978, -1.236067978}
