Simplifying 8n(4n + -5) = 7 Reorder the terms: 8n(-5 + 4n) = 7 (-5 * 8n + 4n * 8n) = 7 (-40n + 32n2) = 7 Solving -40n + 32n2 = 7 Solving for variable 'n'. Reorder the terms: -7 + -40n + 32n2 = 7 + -7 Combine like terms: 7 + -7 = 0 -7 + -40n + 32n2 = 0 Begin completing the square. Divide all terms by 32 the coefficient of the squared term: Divide each side by '32'. -0.21875 + -1.25n + n2 = 0 Move the constant term to the right: Add '0.21875' to each side of the equation. -0.21875 + -1.25n + 0.21875 + n2 = 0 + 0.21875 Reorder the terms: -0.21875 + 0.21875 + -1.25n + n2 = 0 + 0.21875 Combine like terms: -0.21875 + 0.21875 = 0.00000 0.00000 + -1.25n + n2 = 0 + 0.21875 -1.25n + n2 = 0 + 0.21875 Combine like terms: 0 + 0.21875 = 0.21875 -1.25n + n2 = 0.21875 The n term is -1.25n. Take half its coefficient (-0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. -1.25n + 0.390625 + n2 = 0.21875 + 0.390625 Reorder the terms: 0.390625 + -1.25n + n2 = 0.21875 + 0.390625 Combine like terms: 0.21875 + 0.390625 = 0.609375 0.390625 + -1.25n + n2 = 0.609375 Factor a perfect square on the left side: (n + -0.625)(n + -0.625) = 0.609375 Calculate the square root of the right side: 0.78062475 Break this problem into two subproblems by setting (n + -0.625) equal to 0.78062475 and -0.78062475.Subproblem 1
n + -0.625 = 0.78062475 Simplifying n + -0.625 = 0.78062475 Reorder the terms: -0.625 + n = 0.78062475 Solving -0.625 + n = 0.78062475 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + n = 0.78062475 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + n = 0.78062475 + 0.625 n = 0.78062475 + 0.625 Combine like terms: 0.78062475 + 0.625 = 1.40562475 n = 1.40562475 Simplifying n = 1.40562475Subproblem 2
n + -0.625 = -0.78062475 Simplifying n + -0.625 = -0.78062475 Reorder the terms: -0.625 + n = -0.78062475 Solving -0.625 + n = -0.78062475 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + n = -0.78062475 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + n = -0.78062475 + 0.625 n = -0.78062475 + 0.625 Combine like terms: -0.78062475 + 0.625 = -0.15562475 n = -0.15562475 Simplifying n = -0.15562475Solution
