Simplifying 2u2 + -5u + -16 = u2 + 4 Reorder the terms: -16 + -5u + 2u2 = u2 + 4 Reorder the terms: -16 + -5u + 2u2 = 4 + u2 Solving -16 + -5u + 2u2 = 4 + u2 Solving for variable 'u'. Reorder the terms: -16 + -4 + -5u + 2u2 + -1u2 = 4 + u2 + -4 + -1u2 Combine like terms: -16 + -4 = -20 -20 + -5u + 2u2 + -1u2 = 4 + u2 + -4 + -1u2 Combine like terms: 2u2 + -1u2 = 1u2 -20 + -5u + 1u2 = 4 + u2 + -4 + -1u2 Reorder the terms: -20 + -5u + 1u2 = 4 + -4 + u2 + -1u2 Combine like terms: 4 + -4 = 0 -20 + -5u + 1u2 = 0 + u2 + -1u2 -20 + -5u + 1u2 = u2 + -1u2 Combine like terms: u2 + -1u2 = 0 -20 + -5u + 1u2 = 0 Begin completing the square. Move the constant term to the right: Add '20' to each side of the equation. -20 + -5u + 20 + u2 = 0 + 20 Reorder the terms: -20 + 20 + -5u + u2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + -5u + u2 = 0 + 20 -5u + u2 = 0 + 20 Combine like terms: 0 + 20 = 20 -5u + u2 = 20 The u term is -5u. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5u + 6.25 + u2 = 20 + 6.25 Reorder the terms: 6.25 + -5u + u2 = 20 + 6.25 Combine like terms: 20 + 6.25 = 26.25 6.25 + -5u + u2 = 26.25 Factor a perfect square on the left side: (u + -2.5)(u + -2.5) = 26.25 Calculate the square root of the right side: 5.123475383 Break this problem into two subproblems by setting (u + -2.5) equal to 5.123475383 and -5.123475383.Subproblem 1
u + -2.5 = 5.123475383 Simplifying u + -2.5 = 5.123475383 Reorder the terms: -2.5 + u = 5.123475383 Solving -2.5 + u = 5.123475383 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + u = 5.123475383 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + u = 5.123475383 + 2.5 u = 5.123475383 + 2.5 Combine like terms: 5.123475383 + 2.5 = 7.623475383 u = 7.623475383 Simplifying u = 7.623475383Subproblem 2
u + -2.5 = -5.123475383 Simplifying u + -2.5 = -5.123475383 Reorder the terms: -2.5 + u = -5.123475383 Solving -2.5 + u = -5.123475383 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + u = -5.123475383 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + u = -5.123475383 + 2.5 u = -5.123475383 + 2.5 Combine like terms: -5.123475383 + 2.5 = -2.623475383 u = -2.623475383 Simplifying u = -2.623475383Solution
The solution to the problem is based on the solutions from the subproblems. u = {7.623475383, -2.623475383}
