Simplifying 3n2 + 2n + -9 = -3 Reorder the terms: -9 + 2n + 3n2 = -3 Solving -9 + 2n + 3n2 = -3 Solving for variable 'n'. Reorder the terms: -9 + 3 + 2n + 3n2 = -3 + 3 Combine like terms: -9 + 3 = -6 -6 + 2n + 3n2 = -3 + 3 Combine like terms: -3 + 3 = 0 -6 + 2n + 3n2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -2 + 0.6666666667n + n2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + 0.6666666667n + 2 + n2 = 0 + 2 Reorder the terms: -2 + 2 + 0.6666666667n + n2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 0.6666666667n + n2 = 0 + 2 0.6666666667n + n2 = 0 + 2 Combine like terms: 0 + 2 = 2 0.6666666667n + n2 = 2 The n term is 0.6666666667n. Take half its coefficient (0.3333333334). Square it (0.1111111112) and add it to both sides. Add '0.1111111112' to each side of the equation. 0.6666666667n + 0.1111111112 + n2 = 2 + 0.1111111112 Reorder the terms: 0.1111111112 + 0.6666666667n + n2 = 2 + 0.1111111112 Combine like terms: 2 + 0.1111111112 = 2.1111111112 0.1111111112 + 0.6666666667n + n2 = 2.1111111112 Factor a perfect square on the left side: (n + 0.3333333334)(n + 0.3333333334) = 2.1111111112 Calculate the square root of the right side: 1.452966315 Break this problem into two subproblems by setting (n + 0.3333333334) equal to 1.452966315 and -1.452966315.Subproblem 1
n + 0.3333333334 = 1.452966315 Simplifying n + 0.3333333334 = 1.452966315 Reorder the terms: 0.3333333334 + n = 1.452966315 Solving 0.3333333334 + n = 1.452966315 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.3333333334' to each side of the equation. 0.3333333334 + -0.3333333334 + n = 1.452966315 + -0.3333333334 Combine like terms: 0.3333333334 + -0.3333333334 = 0.0000000000 0.0000000000 + n = 1.452966315 + -0.3333333334 n = 1.452966315 + -0.3333333334 Combine like terms: 1.452966315 + -0.3333333334 = 1.1196329816 n = 1.1196329816 Simplifying n = 1.1196329816Subproblem 2
