Simplifying 3u2 + -9u + 5 = 0 Reorder the terms: 5 + -9u + 3u2 = 0 Solving 5 + -9u + 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'. 1.666666667 + -3u + u2 = 0 Move the constant term to the right: Add '-1.666666667' to each side of the equation. 1.666666667 + -3u + -1.666666667 + u2 = 0 + -1.666666667 Reorder the terms: 1.666666667 + -1.666666667 + -3u + u2 = 0 + -1.666666667 Combine like terms: 1.666666667 + -1.666666667 = 0.000000000 0.000000000 + -3u + u2 = 0 + -1.666666667 -3u + u2 = 0 + -1.666666667 Combine like terms: 0 + -1.666666667 = -1.666666667 -3u + u2 = -1.666666667 The u term is -3u. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3u + 2.25 + u2 = -1.666666667 + 2.25 Reorder the terms: 2.25 + -3u + u2 = -1.666666667 + 2.25 Combine like terms: -1.666666667 + 2.25 = 0.583333333 2.25 + -3u + u2 = 0.583333333 Factor a perfect square on the left side: (u + -1.5)(u + -1.5) = 0.583333333 Calculate the square root of the right side: 0.763762616 Break this problem into two subproblems by setting (u + -1.5) equal to 0.763762616 and -0.763762616.Subproblem 1
u + -1.5 = 0.763762616 Simplifying u + -1.5 = 0.763762616 Reorder the terms: -1.5 + u = 0.763762616 Solving -1.5 + u = 0.763762616 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + u = 0.763762616 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + u = 0.763762616 + 1.5 u = 0.763762616 + 1.5 Combine like terms: 0.763762616 + 1.5 = 2.263762616 u = 2.263762616 Simplifying u = 2.263762616Subproblem 2
u + -1.5 = -0.763762616 Simplifying u + -1.5 = -0.763762616 Reorder the terms: -1.5 + u = -0.763762616 Solving -1.5 + u = -0.763762616 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + u = -0.763762616 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + u = -0.763762616 + 1.5 u = -0.763762616 + 1.5 Combine like terms: -0.763762616 + 1.5 = 0.736237384 u = 0.736237384 Simplifying u = 0.736237384Solution
