Simplifying 5u2 + -1u + -2 = 0 Reorder the terms: -2 + -1u + 5u2 = 0 Solving -2 + -1u + 5u2 = 0 Solving for variable 'u'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -0.4 + -0.2u + u2 = 0 Move the constant term to the right: Add '0.4' to each side of the equation. -0.4 + -0.2u + 0.4 + u2 = 0 + 0.4 Reorder the terms: -0.4 + 0.4 + -0.2u + u2 = 0 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + -0.2u + u2 = 0 + 0.4 -0.2u + u2 = 0 + 0.4 Combine like terms: 0 + 0.4 = 0.4 -0.2u + u2 = 0.4 The u term is -0.2u. Take half its coefficient (-0.1). Square it (0.01) and add it to both sides. Add '0.01' to each side of the equation. -0.2u + 0.01 + u2 = 0.4 + 0.01 Reorder the terms: 0.01 + -0.2u + u2 = 0.4 + 0.01 Combine like terms: 0.4 + 0.01 = 0.41 0.01 + -0.2u + u2 = 0.41 Factor a perfect square on the left side: (u + -0.1)(u + -0.1) = 0.41 Calculate the square root of the right side: 0.640312424 Break this problem into two subproblems by setting (u + -0.1) equal to 0.640312424 and -0.640312424.Subproblem 1
u + -0.1 = 0.640312424 Simplifying u + -0.1 = 0.640312424 Reorder the terms: -0.1 + u = 0.640312424 Solving -0.1 + u = 0.640312424 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '0.1' to each side of the equation. -0.1 + 0.1 + u = 0.640312424 + 0.1 Combine like terms: -0.1 + 0.1 = 0.0 0.0 + u = 0.640312424 + 0.1 u = 0.640312424 + 0.1 Combine like terms: 0.640312424 + 0.1 = 0.740312424 u = 0.740312424 Simplifying u = 0.740312424Subproblem 2
u + -0.1 = -0.640312424 Simplifying u + -0.1 = -0.640312424 Reorder the terms: -0.1 + u = -0.640312424 Solving -0.1 + u = -0.640312424 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '0.1' to each side of the equation. -0.1 + 0.1 + u = -0.640312424 + 0.1 Combine like terms: -0.1 + 0.1 = 0.0 0.0 + u = -0.640312424 + 0.1 u = -0.640312424 + 0.1 Combine like terms: -0.640312424 + 0.1 = -0.540312424 u = -0.540312424 Simplifying u = -0.540312424Solution
