Simplifying u2 + 2u + 6u + -12 = 0 Reorder the terms: -12 + 2u + 6u + u2 = 0 Combine like terms: 2u + 6u = 8u -12 + 8u + u2 = 0 Solving -12 + 8u + u2 = 0 Solving for variable 'u'. Begin completing the square. Move the constant term to the right: Add '12' to each side of the equation. -12 + 8u + 12 + u2 = 0 + 12 Reorder the terms: -12 + 12 + 8u + u2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + 8u + u2 = 0 + 12 8u + u2 = 0 + 12 Combine like terms: 0 + 12 = 12 8u + u2 = 12 The u term is 8u. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8u + 16 + u2 = 12 + 16 Reorder the terms: 16 + 8u + u2 = 12 + 16 Combine like terms: 12 + 16 = 28 16 + 8u + u2 = 28 Factor a perfect square on the left side: (u + 4)(u + 4) = 28 Calculate the square root of the right side: 5.291502622 Break this problem into two subproblems by setting (u + 4) equal to 5.291502622 and -5.291502622.Subproblem 1
u + 4 = 5.291502622 Simplifying u + 4 = 5.291502622 Reorder the terms: 4 + u = 5.291502622 Solving 4 + u = 5.291502622 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + u = 5.291502622 + -4 Combine like terms: 4 + -4 = 0 0 + u = 5.291502622 + -4 u = 5.291502622 + -4 Combine like terms: 5.291502622 + -4 = 1.291502622 u = 1.291502622 Simplifying u = 1.291502622Subproblem 2
u + 4 = -5.291502622 Simplifying u + 4 = -5.291502622 Reorder the terms: 4 + u = -5.291502622 Solving 4 + u = -5.291502622 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + u = -5.291502622 + -4 Combine like terms: 4 + -4 = 0 0 + u = -5.291502622 + -4 u = -5.291502622 + -4 Combine like terms: -5.291502622 + -4 = -9.291502622 u = -9.291502622 Simplifying u = -9.291502622Solution
The solution to the problem is based on the solutions from the subproblems. u = {1.291502622, -9.291502622}
