Simplifying 8n2 + 7n + -16 = 0 Reorder the terms: -16 + 7n + 8n2 = 0 Solving -16 + 7n + 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'. -2 + 0.875n + n2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + 0.875n + 2 + n2 = 0 + 2 Reorder the terms: -2 + 2 + 0.875n + n2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 0.875n + n2 = 0 + 2 0.875n + n2 = 0 + 2 Combine like terms: 0 + 2 = 2 0.875n + n2 = 2 The n term is 0.875n. Take half its coefficient (0.4375). Square it (0.19140625) and add it to both sides. Add '0.19140625' to each side of the equation. 0.875n + 0.19140625 + n2 = 2 + 0.19140625 Reorder the terms: 0.19140625 + 0.875n + n2 = 2 + 0.19140625 Combine like terms: 2 + 0.19140625 = 2.19140625 0.19140625 + 0.875n + n2 = 2.19140625 Factor a perfect square on the left side: (n + 0.4375)(n + 0.4375) = 2.19140625 Calculate the square root of the right side: 1.48033991 Break this problem into two subproblems by setting (n + 0.4375) equal to 1.48033991 and -1.48033991.Subproblem 1
n + 0.4375 = 1.48033991 Simplifying n + 0.4375 = 1.48033991 Reorder the terms: 0.4375 + n = 1.48033991 Solving 0.4375 + n = 1.48033991 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.4375' to each side of the equation. 0.4375 + -0.4375 + n = 1.48033991 + -0.4375 Combine like terms: 0.4375 + -0.4375 = 0.0000 0.0000 + n = 1.48033991 + -0.4375 n = 1.48033991 + -0.4375 Combine like terms: 1.48033991 + -0.4375 = 1.04283991 n = 1.04283991 Simplifying n = 1.04283991Subproblem 2
n + 0.4375 = -1.48033991 Simplifying n + 0.4375 = -1.48033991 Reorder the terms: 0.4375 + n = -1.48033991 Solving 0.4375 + n = -1.48033991 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.4375' to each side of the equation. 0.4375 + -0.4375 + n = -1.48033991 + -0.4375 Combine like terms: 0.4375 + -0.4375 = 0.0000 0.0000 + n = -1.48033991 + -0.4375 n = -1.48033991 + -0.4375 Combine like terms: -1.48033991 + -0.4375 = -1.91783991 n = -1.91783991 Simplifying n = -1.91783991Solution
