Simplifying 5n2 + 20n + -68 = -2 Reorder the terms: -68 + 20n + 5n2 = -2 Solving -68 + 20n + 5n2 = -2 Solving for variable 'n'. Reorder the terms: -68 + 2 + 20n + 5n2 = -2 + 2 Combine like terms: -68 + 2 = -66 -66 + 20n + 5n2 = -2 + 2 Combine like terms: -2 + 2 = 0 -66 + 20n + 5n2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -13.2 + 4n + n2 = 0 Move the constant term to the right: Add '13.2' to each side of the equation. -13.2 + 4n + 13.2 + n2 = 0 + 13.2 Reorder the terms: -13.2 + 13.2 + 4n + n2 = 0 + 13.2 Combine like terms: -13.2 + 13.2 = 0.0 0.0 + 4n + n2 = 0 + 13.2 4n + n2 = 0 + 13.2 Combine like terms: 0 + 13.2 = 13.2 4n + n2 = 13.2 The n term is 4n. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4n + 4 + n2 = 13.2 + 4 Reorder the terms: 4 + 4n + n2 = 13.2 + 4 Combine like terms: 13.2 + 4 = 17.2 4 + 4n + n2 = 17.2 Factor a perfect square on the left side: (n + 2)(n + 2) = 17.2 Calculate the square root of the right side: 4.147288271 Break this problem into two subproblems by setting (n + 2) equal to 4.147288271 and -4.147288271.Subproblem 1
n + 2 = 4.147288271 Simplifying n + 2 = 4.147288271 Reorder the terms: 2 + n = 4.147288271 Solving 2 + n = 4.147288271 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + n = 4.147288271 + -2 Combine like terms: 2 + -2 = 0 0 + n = 4.147288271 + -2 n = 4.147288271 + -2 Combine like terms: 4.147288271 + -2 = 2.147288271 n = 2.147288271 Simplifying n = 2.147288271Subproblem 2
n + 2 = -4.147288271 Simplifying n + 2 = -4.147288271 Reorder the terms: 2 + n = -4.147288271 Solving 2 + n = -4.147288271 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + n = -4.147288271 + -2 Combine like terms: 2 + -2 = 0 0 + n = -4.147288271 + -2 n = -4.147288271 + -2 Combine like terms: -4.147288271 + -2 = -6.147288271 n = -6.147288271 Simplifying n = -6.147288271Solution
