Simplifying u(u + -0.25) = 0.0378 Reorder the terms: u(-0.25 + u) = 0.0378 (-0.25 * u + u * u) = 0.0378 (-0.25u + u2) = 0.0378 Solving -0.25u + u2 = 0.0378 Solving for variable 'u'. Reorder the terms: -0.0378 + -0.25u + u2 = 0.0378 + -0.0378 Combine like terms: 0.0378 + -0.0378 = 0.0000 -0.0378 + -0.25u + u2 = 0.0000 Begin completing the square. Move the constant term to the right: Add '0.0378' to each side of the equation. -0.0378 + -0.25u + 0.0378 + u2 = 0.0000 + 0.0378 Reorder the terms: -0.0378 + 0.0378 + -0.25u + u2 = 0.0000 + 0.0378 Combine like terms: -0.0378 + 0.0378 = 0.0000 0.0000 + -0.25u + u2 = 0.0000 + 0.0378 -0.25u + u2 = 0.0000 + 0.0378 Combine like terms: 0.0000 + 0.0378 = 0.0378 -0.25u + u2 = 0.0378 The u term is -0.25u. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25u + 0.015625 + u2 = 0.0378 + 0.015625 Reorder the terms: 0.015625 + -0.25u + u2 = 0.0378 + 0.015625 Combine like terms: 0.0378 + 0.015625 = 0.053425 0.015625 + -0.25u + u2 = 0.053425 Factor a perfect square on the left side: (u + -0.125)(u + -0.125) = 0.053425 Calculate the square root of the right side: 0.231138487 Break this problem into two subproblems by setting (u + -0.125) equal to 0.231138487 and -0.231138487.Subproblem 1
u + -0.125 = 0.231138487 Simplifying u + -0.125 = 0.231138487 Reorder the terms: -0.125 + u = 0.231138487 Solving -0.125 + u = 0.231138487 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + u = 0.231138487 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + u = 0.231138487 + 0.125 u = 0.231138487 + 0.125 Combine like terms: 0.231138487 + 0.125 = 0.356138487 u = 0.356138487 Simplifying u = 0.356138487Subproblem 2
u + -0.125 = -0.231138487 Simplifying u + -0.125 = -0.231138487 Reorder the terms: -0.125 + u = -0.231138487 Solving -0.125 + u = -0.231138487 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + u = -0.231138487 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + u = -0.231138487 + 0.125 u = -0.231138487 + 0.125 Combine like terms: -0.231138487 + 0.125 = -0.106138487 u = -0.106138487 Simplifying u = -0.106138487Solution
The solution to the problem is based on the solutions from the subproblems. u = {0.356138487, -0.106138487}
