Simplifying u2 + -12u + 36 + 3 = 78 Reorder the terms: 36 + 3 + -12u + u2 = 78 Combine like terms: 36 + 3 = 39 39 + -12u + u2 = 78 Solving 39 + -12u + u2 = 78 Solving for variable 'u'. Reorder the terms: 39 + -78 + -12u + u2 = 78 + -78 Combine like terms: 39 + -78 = -39 -39 + -12u + u2 = 78 + -78 Combine like terms: 78 + -78 = 0 -39 + -12u + u2 = 0 Begin completing the square. Move the constant term to the right: Add '39' to each side of the equation. -39 + -12u + 39 + u2 = 0 + 39 Reorder the terms: -39 + 39 + -12u + u2 = 0 + 39 Combine like terms: -39 + 39 = 0 0 + -12u + u2 = 0 + 39 -12u + u2 = 0 + 39 Combine like terms: 0 + 39 = 39 -12u + u2 = 39 The u term is -12u. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12u + 36 + u2 = 39 + 36 Reorder the terms: 36 + -12u + u2 = 39 + 36 Combine like terms: 39 + 36 = 75 36 + -12u + u2 = 75 Factor a perfect square on the left side: (u + -6)(u + -6) = 75 Calculate the square root of the right side: 8.660254038 Break this problem into two subproblems by setting (u + -6) equal to 8.660254038 and -8.660254038.Subproblem 1
u + -6 = 8.660254038 Simplifying u + -6 = 8.660254038 Reorder the terms: -6 + u = 8.660254038 Solving -6 + u = 8.660254038 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + u = 8.660254038 + 6 Combine like terms: -6 + 6 = 0 0 + u = 8.660254038 + 6 u = 8.660254038 + 6 Combine like terms: 8.660254038 + 6 = 14.660254038 u = 14.660254038 Simplifying u = 14.660254038Subproblem 2
u + -6 = -8.660254038 Simplifying u + -6 = -8.660254038 Reorder the terms: -6 + u = -8.660254038 Solving -6 + u = -8.660254038 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + u = -8.660254038 + 6 Combine like terms: -6 + 6 = 0 0 + u = -8.660254038 + 6 u = -8.660254038 + 6 Combine like terms: -8.660254038 + 6 = -2.660254038 u = -2.660254038 Simplifying u = -2.660254038Solution
The solution to the problem is based on the solutions from the subproblems. u = {14.660254038, -2.660254038}
