Simplifying 10 = 0.04v2 + 1.1v Reorder the terms: 10 = 1.1v + 0.04v2 Solving 10 = 1.1v + 0.04v2 Solving for variable 'v'. Reorder the terms: 10 + -1.1v + -0.04v2 = 1.1v + -1.1v + 0.04v2 + -0.04v2 Combine like terms: 1.1v + -1.1v = 0.0 10 + -1.1v + -0.04v2 = 0.0 + 0.04v2 + -0.04v2 10 + -1.1v + -0.04v2 = 0.04v2 + -0.04v2 Combine like terms: 0.04v2 + -0.04v2 = 0.00 10 + -1.1v + -0.04v2 = 0.00 Begin completing the square. Divide all terms by -0.04 the coefficient of the squared term: Divide each side by '-0.04'. -250 + 27.5v + v2 = 0 Move the constant term to the right: Add '250' to each side of the equation. -250 + 27.5v + 250 + v2 = 0 + 250 Reorder the terms: -250 + 250 + 27.5v + v2 = 0 + 250 Combine like terms: -250 + 250 = 0 0 + 27.5v + v2 = 0 + 250 27.5v + v2 = 0 + 250 Combine like terms: 0 + 250 = 250 27.5v + v2 = 250 The v term is 27.5v. Take half its coefficient (13.75). Square it (189.0625) and add it to both sides. Add '189.0625' to each side of the equation. 27.5v + 189.0625 + v2 = 250 + 189.0625 Reorder the terms: 189.0625 + 27.5v + v2 = 250 + 189.0625 Combine like terms: 250 + 189.0625 = 439.0625 189.0625 + 27.5v + v2 = 439.0625 Factor a perfect square on the left side: (v + 13.75)(v + 13.75) = 439.0625 Calculate the square root of the right side: 20.953818268 Break this problem into two subproblems by setting (v + 13.75) equal to 20.953818268 and -20.953818268.Subproblem 1
v + 13.75 = 20.953818268 Simplifying v + 13.75 = 20.953818268 Reorder the terms: 13.75 + v = 20.953818268 Solving 13.75 + v = 20.953818268 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-13.75' to each side of the equation. 13.75 + -13.75 + v = 20.953818268 + -13.75 Combine like terms: 13.75 + -13.75 = 0.00 0.00 + v = 20.953818268 + -13.75 v = 20.953818268 + -13.75 Combine like terms: 20.953818268 + -13.75 = 7.203818268 v = 7.203818268 Simplifying v = 7.203818268Subproblem 2
v + 13.75 = -20.953818268 Simplifying v + 13.75 = -20.953818268 Reorder the terms: 13.75 + v = -20.953818268 Solving 13.75 + v = -20.953818268 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-13.75' to each side of the equation. 13.75 + -13.75 + v = -20.953818268 + -13.75 Combine like terms: 13.75 + -13.75 = 0.00 0.00 + v = -20.953818268 + -13.75 v = -20.953818268 + -13.75 Combine like terms: -20.953818268 + -13.75 = -34.703818268 v = -34.703818268 Simplifying v = -34.703818268Solution
The solution to the problem is based on the solutions from the subproblems. v = {7.203818268, -34.703818268}
