Simplifying u2 + 25 = 2u2 + -13u + 21 Reorder the terms: 25 + u2 = 2u2 + -13u + 21 Reorder the terms: 25 + u2 = 21 + -13u + 2u2 Solving 25 + u2 = 21 + -13u + 2u2 Solving for variable 'u'. Reorder the terms: 25 + -21 + 13u + u2 + -2u2 = 21 + -13u + 2u2 + -21 + 13u + -2u2 Combine like terms: 25 + -21 = 4 4 + 13u + u2 + -2u2 = 21 + -13u + 2u2 + -21 + 13u + -2u2 Combine like terms: u2 + -2u2 = -1u2 4 + 13u + -1u2 = 21 + -13u + 2u2 + -21 + 13u + -2u2 Reorder the terms: 4 + 13u + -1u2 = 21 + -21 + -13u + 13u + 2u2 + -2u2 Combine like terms: 21 + -21 = 0 4 + 13u + -1u2 = 0 + -13u + 13u + 2u2 + -2u2 4 + 13u + -1u2 = -13u + 13u + 2u2 + -2u2 Combine like terms: -13u + 13u = 0 4 + 13u + -1u2 = 0 + 2u2 + -2u2 4 + 13u + -1u2 = 2u2 + -2u2 Combine like terms: 2u2 + -2u2 = 0 4 + 13u + -1u2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -4 + -13u + u2 = 0 Move the constant term to the right: Add '4' to each side of the equation. -4 + -13u + 4 + u2 = 0 + 4 Reorder the terms: -4 + 4 + -13u + u2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -13u + u2 = 0 + 4 -13u + u2 = 0 + 4 Combine like terms: 0 + 4 = 4 -13u + u2 = 4 The u term is -13u. Take half its coefficient (-6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. -13u + 42.25 + u2 = 4 + 42.25 Reorder the terms: 42.25 + -13u + u2 = 4 + 42.25 Combine like terms: 4 + 42.25 = 46.25 42.25 + -13u + u2 = 46.25 Factor a perfect square on the left side: (u + -6.5)(u + -6.5) = 46.25 Calculate the square root of the right side: 6.800735254 Break this problem into two subproblems by setting (u + -6.5) equal to 6.800735254 and -6.800735254.Subproblem 1
u + -6.5 = 6.800735254 Simplifying u + -6.5 = 6.800735254 Reorder the terms: -6.5 + u = 6.800735254 Solving -6.5 + u = 6.800735254 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '6.5' to each side of the equation. -6.5 + 6.5 + u = 6.800735254 + 6.5 Combine like terms: -6.5 + 6.5 = 0.0 0.0 + u = 6.800735254 + 6.5 u = 6.800735254 + 6.5 Combine like terms: 6.800735254 + 6.5 = 13.300735254 u = 13.300735254 Simplifying u = 13.300735254Subproblem 2
u + -6.5 = -6.800735254 Simplifying u + -6.5 = -6.800735254 Reorder the terms: -6.5 + u = -6.800735254 Solving -6.5 + u = -6.800735254 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '6.5' to each side of the equation. -6.5 + 6.5 + u = -6.800735254 + 6.5 Combine like terms: -6.5 + 6.5 = 0.0 0.0 + u = -6.800735254 + 6.5 u = -6.800735254 + 6.5 Combine like terms: -6.800735254 + 6.5 = -0.300735254 u = -0.300735254 Simplifying u = -0.300735254Solution
The solution to the problem is based on the solutions from the subproblems. u = {13.300735254, -0.300735254}
