Simplifying u2 + -20u = 30 Reorder the terms: -20u + u2 = 30 Solving -20u + u2 = 30 Solving for variable 'u'. Reorder the terms: -30 + -20u + u2 = 30 + -30 Combine like terms: 30 + -30 = 0 -30 + -20u + u2 = 0 Begin completing the square. Move the constant term to the right: Add '30' to each side of the equation. -30 + -20u + 30 + u2 = 0 + 30 Reorder the terms: -30 + 30 + -20u + u2 = 0 + 30 Combine like terms: -30 + 30 = 0 0 + -20u + u2 = 0 + 30 -20u + u2 = 0 + 30 Combine like terms: 0 + 30 = 30 -20u + u2 = 30 The u term is -20u. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20u + 100 + u2 = 30 + 100 Reorder the terms: 100 + -20u + u2 = 30 + 100 Combine like terms: 30 + 100 = 130 100 + -20u + u2 = 130 Factor a perfect square on the left side: (u + -10)(u + -10) = 130 Calculate the square root of the right side: 11.401754251 Break this problem into two subproblems by setting (u + -10) equal to 11.401754251 and -11.401754251.Subproblem 1
u + -10 = 11.401754251 Simplifying u + -10 = 11.401754251 Reorder the terms: -10 + u = 11.401754251 Solving -10 + u = 11.401754251 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + u = 11.401754251 + 10 Combine like terms: -10 + 10 = 0 0 + u = 11.401754251 + 10 u = 11.401754251 + 10 Combine like terms: 11.401754251 + 10 = 21.401754251 u = 21.401754251 Simplifying u = 21.401754251Subproblem 2
u + -10 = -11.401754251 Simplifying u + -10 = -11.401754251 Reorder the terms: -10 + u = -11.401754251 Solving -10 + u = -11.401754251 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + u = -11.401754251 + 10 Combine like terms: -10 + 10 = 0 0 + u = -11.401754251 + 10 u = -11.401754251 + 10 Combine like terms: -11.401754251 + 10 = -1.401754251 u = -1.401754251 Simplifying u = -1.401754251Solution
The solution to the problem is based on the solutions from the subproblems. u = {21.401754251, -1.401754251}
