Simplifying 8n2 + -51n + -56 = 0 Reorder the terms: -56 + -51n + 8n2 = 0 Solving -56 + -51n + 8n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -7 + -6.375n + n2 = 0 Move the constant term to the right: Add '7' to each side of the equation. -7 + -6.375n + 7 + n2 = 0 + 7 Reorder the terms: -7 + 7 + -6.375n + n2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -6.375n + n2 = 0 + 7 -6.375n + n2 = 0 + 7 Combine like terms: 0 + 7 = 7 -6.375n + n2 = 7 The n term is -6.375n. Take half its coefficient (-3.1875). Square it (10.16015625) and add it to both sides. Add '10.16015625' to each side of the equation. -6.375n + 10.16015625 + n2 = 7 + 10.16015625 Reorder the terms: 10.16015625 + -6.375n + n2 = 7 + 10.16015625 Combine like terms: 7 + 10.16015625 = 17.16015625 10.16015625 + -6.375n + n2 = 17.16015625 Factor a perfect square on the left side: (n + -3.1875)(n + -3.1875) = 17.16015625 Calculate the square root of the right side: 4.142481895 Break this problem into two subproblems by setting (n + -3.1875) equal to 4.142481895 and -4.142481895.Subproblem 1
n + -3.1875 = 4.142481895 Simplifying n + -3.1875 = 4.142481895 Reorder the terms: -3.1875 + n = 4.142481895 Solving -3.1875 + n = 4.142481895 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '3.1875' to each side of the equation. -3.1875 + 3.1875 + n = 4.142481895 + 3.1875 Combine like terms: -3.1875 + 3.1875 = 0.0000 0.0000 + n = 4.142481895 + 3.1875 n = 4.142481895 + 3.1875 Combine like terms: 4.142481895 + 3.1875 = 7.329981895 n = 7.329981895 Simplifying n = 7.329981895Subproblem 2
n + -3.1875 = -4.142481895 Simplifying n + -3.1875 = -4.142481895 Reorder the terms: -3.1875 + n = -4.142481895 Solving -3.1875 + n = -4.142481895 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '3.1875' to each side of the equation. -3.1875 + 3.1875 + n = -4.142481895 + 3.1875 Combine like terms: -3.1875 + 3.1875 = 0.0000 0.0000 + n = -4.142481895 + 3.1875 n = -4.142481895 + 3.1875 Combine like terms: -4.142481895 + 3.1875 = -0.954981895 n = -0.954981895 Simplifying n = -0.954981895Solution
