Simplifying 6n2 + -9n + -3 = 0 Reorder the terms: -3 + -9n + 6n2 = 0 Solving -3 + -9n + 6n2 = 0 Solving for variable 'n'. Factor out the Greatest Common Factor (GCF), '3'. 3(-1 + -3n + 2n2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-1 + -3n + 2n2)' equal to zero and attempt to solve: Simplifying -1 + -3n + 2n2 = 0 Solving -1 + -3n + 2n2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -0.5 + -1.5n + n2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + -1.5n + 0.5 + n2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + -1.5n + n2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + -1.5n + n2 = 0 + 0.5 -1.5n + n2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 -1.5n + n2 = 0.5 The n term is -1.5n. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5n + 0.5625 + n2 = 0.5 + 0.5625 Reorder the terms: 0.5625 + -1.5n + n2 = 0.5 + 0.5625 Combine like terms: 0.5 + 0.5625 = 1.0625 0.5625 + -1.5n + n2 = 1.0625 Factor a perfect square on the left side: (n + -0.75)(n + -0.75) = 1.0625 Calculate the square root of the right side: 1.030776406 Break this problem into two subproblems by setting (n + -0.75) equal to 1.030776406 and -1.030776406.Subproblem 1
n + -0.75 = 1.030776406 Simplifying n + -0.75 = 1.030776406 Reorder the terms: -0.75 + n = 1.030776406 Solving -0.75 + n = 1.030776406 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + n = 1.030776406 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + n = 1.030776406 + 0.75 n = 1.030776406 + 0.75 Combine like terms: 1.030776406 + 0.75 = 1.780776406 n = 1.780776406 Simplifying n = 1.780776406Subproblem 2
n + -0.75 = -1.030776406 Simplifying n + -0.75 = -1.030776406 Reorder the terms: -0.75 + n = -1.030776406 Solving -0.75 + n = -1.030776406 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + n = -1.030776406 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + n = -1.030776406 + 0.75 n = -1.030776406 + 0.75 Combine like terms: -1.030776406 + 0.75 = -0.280776406 n = -0.280776406 Simplifying n = -0.280776406Solution
