Simplifying 4n2 + -3n + -13 = 0 Reorder the terms: -13 + -3n + 4n2 = 0 Solving -13 + -3n + 4n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -3.25 + -0.75n + n2 = 0 Move the constant term to the right: Add '3.25' to each side of the equation. -3.25 + -0.75n + 3.25 + n2 = 0 + 3.25 Reorder the terms: -3.25 + 3.25 + -0.75n + n2 = 0 + 3.25 Combine like terms: -3.25 + 3.25 = 0.00 0.00 + -0.75n + n2 = 0 + 3.25 -0.75n + n2 = 0 + 3.25 Combine like terms: 0 + 3.25 = 3.25 -0.75n + n2 = 3.25 The n term is -0.75n. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75n + 0.140625 + n2 = 3.25 + 0.140625 Reorder the terms: 0.140625 + -0.75n + n2 = 3.25 + 0.140625 Combine like terms: 3.25 + 0.140625 = 3.390625 0.140625 + -0.75n + n2 = 3.390625 Factor a perfect square on the left side: (n + -0.375)(n + -0.375) = 3.390625 Calculate the square root of the right side: 1.841364983 Break this problem into two subproblems by setting (n + -0.375) equal to 1.841364983 and -1.841364983.Subproblem 1
n + -0.375 = 1.841364983 Simplifying n + -0.375 = 1.841364983 Reorder the terms: -0.375 + n = 1.841364983 Solving -0.375 + n = 1.841364983 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + n = 1.841364983 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + n = 1.841364983 + 0.375 n = 1.841364983 + 0.375 Combine like terms: 1.841364983 + 0.375 = 2.216364983 n = 2.216364983 Simplifying n = 2.216364983Subproblem 2
n + -0.375 = -1.841364983 Simplifying n + -0.375 = -1.841364983 Reorder the terms: -0.375 + n = -1.841364983 Solving -0.375 + n = -1.841364983 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + n = -1.841364983 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + n = -1.841364983 + 0.375 n = -1.841364983 + 0.375 Combine like terms: -1.841364983 + 0.375 = -1.466364983 n = -1.466364983 Simplifying n = -1.466364983Solution
