Simplifying 2n2 + -11n + 13 = 0 Reorder the terms: 13 + -11n + 2n2 = 0 Solving 13 + -11n + 2n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 6.5 + -5.5n + n2 = 0 Move the constant term to the right: Add '-6.5' to each side of the equation. 6.5 + -5.5n + -6.5 + n2 = 0 + -6.5 Reorder the terms: 6.5 + -6.5 + -5.5n + n2 = 0 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + -5.5n + n2 = 0 + -6.5 -5.5n + n2 = 0 + -6.5 Combine like terms: 0 + -6.5 = -6.5 -5.5n + n2 = -6.5 The n term is -5.5n. Take half its coefficient (-2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. -5.5n + 7.5625 + n2 = -6.5 + 7.5625 Reorder the terms: 7.5625 + -5.5n + n2 = -6.5 + 7.5625 Combine like terms: -6.5 + 7.5625 = 1.0625 7.5625 + -5.5n + n2 = 1.0625 Factor a perfect square on the left side: (n + -2.75)(n + -2.75) = 1.0625 Calculate the square root of the right side: 1.030776406 Break this problem into two subproblems by setting (n + -2.75) equal to 1.030776406 and -1.030776406.Subproblem 1
n + -2.75 = 1.030776406 Simplifying n + -2.75 = 1.030776406 Reorder the terms: -2.75 + n = 1.030776406 Solving -2.75 + n = 1.030776406 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + n = 1.030776406 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + n = 1.030776406 + 2.75 n = 1.030776406 + 2.75 Combine like terms: 1.030776406 + 2.75 = 3.780776406 n = 3.780776406 Simplifying n = 3.780776406Subproblem 2
n + -2.75 = -1.030776406 Simplifying n + -2.75 = -1.030776406 Reorder the terms: -2.75 + n = -1.030776406 Solving -2.75 + n = -1.030776406 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + n = -1.030776406 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + n = -1.030776406 + 2.75 n = -1.030776406 + 2.75 Combine like terms: -1.030776406 + 2.75 = 1.719223594 n = 1.719223594 Simplifying n = 1.719223594Solution
