Simplifying n2 + -10n + 13 = 0 Reorder the terms: 13 + -10n + n2 = 0 Solving 13 + -10n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + -10n + -13 + n2 = 0 + -13 Reorder the terms: 13 + -13 + -10n + n2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -10n + n2 = 0 + -13 -10n + n2 = 0 + -13 Combine like terms: 0 + -13 = -13 -10n + n2 = -13 The n term is -10n. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10n + 25 + n2 = -13 + 25 Reorder the terms: 25 + -10n + n2 = -13 + 25 Combine like terms: -13 + 25 = 12 25 + -10n + n2 = 12 Factor a perfect square on the left side: (n + -5)(n + -5) = 12 Calculate the square root of the right side: 3.464101615 Break this problem into two subproblems by setting (n + -5) equal to 3.464101615 and -3.464101615.Subproblem 1
n + -5 = 3.464101615 Simplifying n + -5 = 3.464101615 Reorder the terms: -5 + n = 3.464101615 Solving -5 + n = 3.464101615 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + n = 3.464101615 + 5 Combine like terms: -5 + 5 = 0 0 + n = 3.464101615 + 5 n = 3.464101615 + 5 Combine like terms: 3.464101615 + 5 = 8.464101615 n = 8.464101615 Simplifying n = 8.464101615Subproblem 2
