Simplifying u + -16u2 + -3 = 0 Reorder the terms: -3 + u + -16u2 = 0 Solving -3 + u + -16u2 = 0 Solving for variable 'u'. Begin completing the square. Divide all terms by -16 the coefficient of the squared term: Divide each side by '-16'. 0.1875 + -0.0625u + u2 = 0 Move the constant term to the right: Add '-0.1875' to each side of the equation. 0.1875 + -0.0625u + -0.1875 + u2 = 0 + -0.1875 Reorder the terms: 0.1875 + -0.1875 + -0.0625u + u2 = 0 + -0.1875 Combine like terms: 0.1875 + -0.1875 = 0.0000 0.0000 + -0.0625u + u2 = 0 + -0.1875 -0.0625u + u2 = 0 + -0.1875 Combine like terms: 0 + -0.1875 = -0.1875 -0.0625u + u2 = -0.1875 The u term is u. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -0.0625u + 0.25 + u2 = -0.1875 + 0.25 Reorder the terms: 0.25 + -0.0625u + u2 = -0.1875 + 0.25 Combine like terms: -0.1875 + 0.25 = 0.0625 0.25 + -0.0625u + u2 = 0.0625 Factor a perfect square on the left side: (u + 0.5)(u + 0.5) = 0.0625 Calculate the square root of the right side: 0.25 Break this problem into two subproblems by setting (u + 0.5) equal to 0.25 and -0.25.Subproblem 1
u + 0.5 = 0.25 Simplifying u + 0.5 = 0.25 Reorder the terms: 0.5 + u = 0.25 Solving 0.5 + u = 0.25 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + u = 0.25 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + u = 0.25 + -0.5 u = 0.25 + -0.5 Combine like terms: 0.25 + -0.5 = -0.25 u = -0.25 Simplifying u = -0.25Subproblem 2
u + 0.5 = -0.25 Simplifying u + 0.5 = -0.25 Reorder the terms: 0.5 + u = -0.25 Solving 0.5 + u = -0.25 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + u = -0.25 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + u = -0.25 + -0.5 u = -0.25 + -0.5 Combine like terms: -0.25 + -0.5 = -0.75 u = -0.75 Simplifying u = -0.75Solution
The solution to the problem is based on the solutions from the subproblems. u = {-0.25, -0.75}
