Simplifying 3u2 + 2u + -9 = 0 Reorder the terms: -9 + 2u + 3u2 = 0 Solving -9 + 2u + 3u2 = 0 Solving for variable 'u'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -3 + 0.6666666667u + u2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + 0.6666666667u + 3 + u2 = 0 + 3 Reorder the terms: -3 + 3 + 0.6666666667u + u2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 0.6666666667u + u2 = 0 + 3 0.6666666667u + u2 = 0 + 3 Combine like terms: 0 + 3 = 3 0.6666666667u + u2 = 3 The u term is 0.6666666667u. 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. 0.6666666667u + 0.1111111112 + u2 = 3 + 0.1111111112 Reorder the terms: 0.1111111112 + 0.6666666667u + u2 = 3 + 0.1111111112 Combine like terms: 3 + 0.1111111112 = 3.1111111112 0.1111111112 + 0.6666666667u + u2 = 3.1111111112 Factor a perfect square on the left side: (u + 0.3333333334)(u + 0.3333333334) = 3.1111111112 Calculate the square root of the right side: 1.763834207 Break this problem into two subproblems by setting (u + 0.3333333334) equal to 1.763834207 and -1.763834207.Subproblem 1
u + 0.3333333334 = 1.763834207 Simplifying u + 0.3333333334 = 1.763834207 Reorder the terms: 0.3333333334 + u = 1.763834207 Solving 0.3333333334 + u = 1.763834207 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-0.3333333334' to each side of the equation. 0.3333333334 + -0.3333333334 + u = 1.763834207 + -0.3333333334 Combine like terms: 0.3333333334 + -0.3333333334 = 0.0000000000 0.0000000000 + u = 1.763834207 + -0.3333333334 u = 1.763834207 + -0.3333333334 Combine like terms: 1.763834207 + -0.3333333334 = 1.4305008736 u = 1.4305008736 Simplifying u = 1.4305008736Subproblem 2
u + 0.3333333334 = -1.763834207 Simplifying u + 0.3333333334 = -1.763834207 Reorder the terms: 0.3333333334 + u = -1.763834207 Solving 0.3333333334 + u = -1.763834207 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-0.3333333334' to each side of the equation. 0.3333333334 + -0.3333333334 + u = -1.763834207 + -0.3333333334 Combine like terms: 0.3333333334 + -0.3333333334 = 0.0000000000 0.0000000000 + u = -1.763834207 + -0.3333333334 u = -1.763834207 + -0.3333333334 Combine like terms: -1.763834207 + -0.3333333334 = -2.0971675404 u = -2.0971675404 Simplifying u = -2.0971675404Solution
