Simplifying 8u2 + 18u + -8 = 0 Reorder the terms: -8 + 18u + 8u2 = 0 Solving -8 + 18u + 8u2 = 0 Solving for variable 'u'. Factor out the Greatest Common Factor (GCF), '2'. 2(-4 + 9u + 4u2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-4 + 9u + 4u2)' equal to zero and attempt to solve: Simplifying -4 + 9u + 4u2 = 0 Solving -4 + 9u + 4u2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -1 + 2.25u + u2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + 2.25u + 1 + u2 = 0 + 1 Reorder the terms: -1 + 1 + 2.25u + u2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 2.25u + u2 = 0 + 1 2.25u + u2 = 0 + 1 Combine like terms: 0 + 1 = 1 2.25u + u2 = 1 The u term is 2.25u. Take half its coefficient (1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. 2.25u + 1.265625 + u2 = 1 + 1.265625 Reorder the terms: 1.265625 + 2.25u + u2 = 1 + 1.265625 Combine like terms: 1 + 1.265625 = 2.265625 1.265625 + 2.25u + u2 = 2.265625 Factor a perfect square on the left side: (u + 1.125)(u + 1.125) = 2.265625 Calculate the square root of the right side: 1.505199322 Break this problem into two subproblems by setting (u + 1.125) equal to 1.505199322 and -1.505199322.Subproblem 1
u + 1.125 = 1.505199322 Simplifying u + 1.125 = 1.505199322 Reorder the terms: 1.125 + u = 1.505199322 Solving 1.125 + u = 1.505199322 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-1.125' to each side of the equation. 1.125 + -1.125 + u = 1.505199322 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + u = 1.505199322 + -1.125 u = 1.505199322 + -1.125 Combine like terms: 1.505199322 + -1.125 = 0.380199322 u = 0.380199322 Simplifying u = 0.380199322Subproblem 2
u + 1.125 = -1.505199322 Simplifying u + 1.125 = -1.505199322 Reorder the terms: 1.125 + u = -1.505199322 Solving 1.125 + u = -1.505199322 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-1.125' to each side of the equation. 1.125 + -1.125 + u = -1.505199322 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + u = -1.505199322 + -1.125 u = -1.505199322 + -1.125 Combine like terms: -1.505199322 + -1.125 = -2.630199322 u = -2.630199322 Simplifying u = -2.630199322Solution
The solution to the problem is based on the solutions from the subproblems. u = {0.380199322, -2.630199322}Solution
u = {0.380199322, -2.630199322}
