Simplifying 2u2 + 17u + -28 = 0 Reorder the terms: -28 + 17u + 2u2 = 0 Solving -28 + 17u + 2u2 = 0 Solving for variable 'u'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -14 + 8.5u + u2 = 0 Move the constant term to the right: Add '14' to each side of the equation. -14 + 8.5u + 14 + u2 = 0 + 14 Reorder the terms: -14 + 14 + 8.5u + u2 = 0 + 14 Combine like terms: -14 + 14 = 0 0 + 8.5u + u2 = 0 + 14 8.5u + u2 = 0 + 14 Combine like terms: 0 + 14 = 14 8.5u + u2 = 14 The u term is 8.5u. Take half its coefficient (4.25). Square it (18.0625) and add it to both sides. Add '18.0625' to each side of the equation. 8.5u + 18.0625 + u2 = 14 + 18.0625 Reorder the terms: 18.0625 + 8.5u + u2 = 14 + 18.0625 Combine like terms: 14 + 18.0625 = 32.0625 18.0625 + 8.5u + u2 = 32.0625 Factor a perfect square on the left side: (u + 4.25)(u + 4.25) = 32.0625 Calculate the square root of the right side: 5.662375826 Break this problem into two subproblems by setting (u + 4.25) equal to 5.662375826 and -5.662375826.Subproblem 1
u + 4.25 = 5.662375826 Simplifying u + 4.25 = 5.662375826 Reorder the terms: 4.25 + u = 5.662375826 Solving 4.25 + u = 5.662375826 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + u = 5.662375826 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + u = 5.662375826 + -4.25 u = 5.662375826 + -4.25 Combine like terms: 5.662375826 + -4.25 = 1.412375826 u = 1.412375826 Simplifying u = 1.412375826Subproblem 2
u + 4.25 = -5.662375826 Simplifying u + 4.25 = -5.662375826 Reorder the terms: 4.25 + u = -5.662375826 Solving 4.25 + u = -5.662375826 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + u = -5.662375826 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + u = -5.662375826 + -4.25 u = -5.662375826 + -4.25 Combine like terms: -5.662375826 + -4.25 = -9.912375826 u = -9.912375826 Simplifying u = -9.912375826Solution
