Simplifying u2 + -12u + -15 = 0 Reorder the terms: -15 + -12u + u2 = 0 Solving -15 + -12u + u2 = 0 Solving for variable 'u'. Begin completing the square. Move the constant term to the right: Add '15' to each side of the equation. -15 + -12u + 15 + u2 = 0 + 15 Reorder the terms: -15 + 15 + -12u + u2 = 0 + 15 Combine like terms: -15 + 15 = 0 0 + -12u + u2 = 0 + 15 -12u + u2 = 0 + 15 Combine like terms: 0 + 15 = 15 -12u + u2 = 15 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 = 15 + 36 Reorder the terms: 36 + -12u + u2 = 15 + 36 Combine like terms: 15 + 36 = 51 36 + -12u + u2 = 51 Factor a perfect square on the left side: (u + -6)(u + -6) = 51 Calculate the square root of the right side: 7.141428429 Break this problem into two subproblems by setting (u + -6) equal to 7.141428429 and -7.141428429.Subproblem 1
u + -6 = 7.141428429 Simplifying u + -6 = 7.141428429 Reorder the terms: -6 + u = 7.141428429 Solving -6 + u = 7.141428429 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 = 7.141428429 + 6 Combine like terms: -6 + 6 = 0 0 + u = 7.141428429 + 6 u = 7.141428429 + 6 Combine like terms: 7.141428429 + 6 = 13.141428429 u = 13.141428429 Simplifying u = 13.141428429Subproblem 2
u + -6 = -7.141428429 Simplifying u + -6 = -7.141428429 Reorder the terms: -6 + u = -7.141428429 Solving -6 + u = -7.141428429 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 = -7.141428429 + 6 Combine like terms: -6 + 6 = 0 0 + u = -7.141428429 + 6 u = -7.141428429 + 6 Combine like terms: -7.141428429 + 6 = -1.141428429 u = -1.141428429 Simplifying u = -1.141428429Solution
The solution to the problem is based on the solutions from the subproblems. u = {13.141428429, -1.141428429}
