Simplifying 2n2 + -13n + 5 = 0 Reorder the terms: 5 + -13n + 2n2 = 0 Solving 5 + -13n + 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'. 2.5 + -6.5n + n2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + -6.5n + -2.5 + n2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + -6.5n + n2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + -6.5n + n2 = 0 + -2.5 -6.5n + n2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 -6.5n + n2 = -2.5 The n term is -6.5n. Take half its coefficient (-3.25). Square it (10.5625) and add it to both sides. Add '10.5625' to each side of the equation. -6.5n + 10.5625 + n2 = -2.5 + 10.5625 Reorder the terms: 10.5625 + -6.5n + n2 = -2.5 + 10.5625 Combine like terms: -2.5 + 10.5625 = 8.0625 10.5625 + -6.5n + n2 = 8.0625 Factor a perfect square on the left side: (n + -3.25)(n + -3.25) = 8.0625 Calculate the square root of the right side: 2.839454173 Break this problem into two subproblems by setting (n + -3.25) equal to 2.839454173 and -2.839454173.Subproblem 1
n + -3.25 = 2.839454173 Simplifying n + -3.25 = 2.839454173 Reorder the terms: -3.25 + n = 2.839454173 Solving -3.25 + n = 2.839454173 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '3.25' to each side of the equation. -3.25 + 3.25 + n = 2.839454173 + 3.25 Combine like terms: -3.25 + 3.25 = 0.00 0.00 + n = 2.839454173 + 3.25 n = 2.839454173 + 3.25 Combine like terms: 2.839454173 + 3.25 = 6.089454173 n = 6.089454173 Simplifying n = 6.089454173Subproblem 2
n + -3.25 = -2.839454173 Simplifying n + -3.25 = -2.839454173 Reorder the terms: -3.25 + n = -2.839454173 Solving -3.25 + n = -2.839454173 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '3.25' to each side of the equation. -3.25 + 3.25 + n = -2.839454173 + 3.25 Combine like terms: -3.25 + 3.25 = 0.00 0.00 + n = -2.839454173 + 3.25 n = -2.839454173 + 3.25 Combine like terms: -2.839454173 + 3.25 = 0.410545827 n = 0.410545827 Simplifying n = 0.410545827Solution
