Simplifying u2 + -4u + 2 = 0 Reorder the terms: 2 + -4u + u2 = 0 Solving 2 + -4u + u2 = 0 Solving for variable 'u'. Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + -4u + -2 + u2 = 0 + -2 Reorder the terms: 2 + -2 + -4u + u2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -4u + u2 = 0 + -2 -4u + u2 = 0 + -2 Combine like terms: 0 + -2 = -2 -4u + u2 = -2 The u term is -4u. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4u + 4 + u2 = -2 + 4 Reorder the terms: 4 + -4u + u2 = -2 + 4 Combine like terms: -2 + 4 = 2 4 + -4u + u2 = 2 Factor a perfect square on the left side: (u + -2)(u + -2) = 2 Calculate the square root of the right side: 1.414213562 Break this problem into two subproblems by setting (u + -2) equal to 1.414213562 and -1.414213562.Subproblem 1
u + -2 = 1.414213562 Simplifying u + -2 = 1.414213562 Reorder the terms: -2 + u = 1.414213562 Solving -2 + u = 1.414213562 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + u = 1.414213562 + 2 Combine like terms: -2 + 2 = 0 0 + u = 1.414213562 + 2 u = 1.414213562 + 2 Combine like terms: 1.414213562 + 2 = 3.414213562 u = 3.414213562 Simplifying u = 3.414213562Subproblem 2
u + -2 = -1.414213562 Simplifying u + -2 = -1.414213562 Reorder the terms: -2 + u = -1.414213562 Solving -2 + u = -1.414213562 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + u = -1.414213562 + 2 Combine like terms: -2 + 2 = 0 0 + u = -1.414213562 + 2 u = -1.414213562 + 2 Combine like terms: -1.414213562 + 2 = 0.585786438 u = 0.585786438 Simplifying u = 0.585786438Solution
The solution to the problem is based on the solutions from the subproblems. u = {3.414213562, 0.585786438}
