Simplifying u2 + -12u + 7 = 0 Reorder the terms: 7 + -12u + u2 = 0 Solving 7 + -12u + u2 = 0 Solving for variable 'u'. Begin completing the square. Move the constant term to the right: Add '-7' to each side of the equation. 7 + -12u + -7 + u2 = 0 + -7 Reorder the terms: 7 + -7 + -12u + u2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -12u + u2 = 0 + -7 -12u + u2 = 0 + -7 Combine like terms: 0 + -7 = -7 -12u + u2 = -7 The u term is -12u. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12u + 36 + u2 = -7 + 36 Reorder the terms: 36 + -12u + u2 = -7 + 36 Combine like terms: -7 + 36 = 29 36 + -12u + u2 = 29 Factor a perfect square on the left side: (u + -6)(u + -6) = 29 Calculate the square root of the right side: 5.385164807 Break this problem into two subproblems by setting (u + -6) equal to 5.385164807 and -5.385164807.Subproblem 1
u + -6 = 5.385164807 Simplifying u + -6 = 5.385164807 Reorder the terms: -6 + u = 5.385164807 Solving -6 + u = 5.385164807 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + u = 5.385164807 + 6 Combine like terms: -6 + 6 = 0 0 + u = 5.385164807 + 6 u = 5.385164807 + 6 Combine like terms: 5.385164807 + 6 = 11.385164807 u = 11.385164807 Simplifying u = 11.385164807Subproblem 2
u + -6 = -5.385164807 Simplifying u + -6 = -5.385164807 Reorder the terms: -6 + u = -5.385164807 Solving -6 + u = -5.385164807 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + u = -5.385164807 + 6 Combine like terms: -6 + 6 = 0 0 + u = -5.385164807 + 6 u = -5.385164807 + 6 Combine like terms: -5.385164807 + 6 = 0.614835193 u = 0.614835193 Simplifying u = 0.614835193Solution
The solution to the problem is based on the solutions from the subproblems. u = {11.385164807, 0.614835193}
