Simplifying 8n2 + -4n + -18 = 9 Reorder the terms: -18 + -4n + 8n2 = 9 Solving -18 + -4n + 8n2 = 9 Solving for variable 'n'. Reorder the terms: -18 + -9 + -4n + 8n2 = 9 + -9 Combine like terms: -18 + -9 = -27 -27 + -4n + 8n2 = 9 + -9 Combine like terms: 9 + -9 = 0 -27 + -4n + 8n2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -3.375 + -0.5n + n2 = 0 Move the constant term to the right: Add '3.375' to each side of the equation. -3.375 + -0.5n + 3.375 + n2 = 0 + 3.375 Reorder the terms: -3.375 + 3.375 + -0.5n + n2 = 0 + 3.375 Combine like terms: -3.375 + 3.375 = 0.000 0.000 + -0.5n + n2 = 0 + 3.375 -0.5n + n2 = 0 + 3.375 Combine like terms: 0 + 3.375 = 3.375 -0.5n + n2 = 3.375 The n term is -0.5n. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5n + 0.0625 + n2 = 3.375 + 0.0625 Reorder the terms: 0.0625 + -0.5n + n2 = 3.375 + 0.0625 Combine like terms: 3.375 + 0.0625 = 3.4375 0.0625 + -0.5n + n2 = 3.4375 Factor a perfect square on the left side: (n + -0.25)(n + -0.25) = 3.4375 Calculate the square root of the right side: 1.854049622 Break this problem into two subproblems by setting (n + -0.25) equal to 1.854049622 and -1.854049622.Subproblem 1
n + -0.25 = 1.854049622 Simplifying n + -0.25 = 1.854049622 Reorder the terms: -0.25 + n = 1.854049622 Solving -0.25 + n = 1.854049622 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + n = 1.854049622 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + n = 1.854049622 + 0.25 n = 1.854049622 + 0.25 Combine like terms: 1.854049622 + 0.25 = 2.104049622 n = 2.104049622 Simplifying n = 2.104049622Subproblem 2
n + -0.25 = -1.854049622 Simplifying n + -0.25 = -1.854049622 Reorder the terms: -0.25 + n = -1.854049622 Solving -0.25 + n = -1.854049622 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + n = -1.854049622 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + n = -1.854049622 + 0.25 n = -1.854049622 + 0.25 Combine like terms: -1.854049622 + 0.25 = -1.604049622 n = -1.604049622 Simplifying n = -1.604049622Solution
