Simplifying 8v2 + v + -4 = 0 Reorder the terms: -4 + v + 8v2 = 0 Solving -4 + v + 8v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -0.5 + 0.125v + v2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + 0.125v + 0.5 + v2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + 0.125v + v2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + 0.125v + v2 = 0 + 0.5 0.125v + v2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 0.125v + v2 = 0.5 The v term is v. 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. 0.125v + 0.25 + v2 = 0.5 + 0.25 Reorder the terms: 0.25 + 0.125v + v2 = 0.5 + 0.25 Combine like terms: 0.5 + 0.25 = 0.75 0.25 + 0.125v + v2 = 0.75 Factor a perfect square on the left side: (v + 0.5)(v + 0.5) = 0.75 Calculate the square root of the right side: 0.866025404 Break this problem into two subproblems by setting (v + 0.5) equal to 0.866025404 and -0.866025404.Subproblem 1
v + 0.5 = 0.866025404 Simplifying v + 0.5 = 0.866025404 Reorder the terms: 0.5 + v = 0.866025404 Solving 0.5 + v = 0.866025404 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + v = 0.866025404 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + v = 0.866025404 + -0.5 v = 0.866025404 + -0.5 Combine like terms: 0.866025404 + -0.5 = 0.366025404 v = 0.366025404 Simplifying v = 0.366025404Subproblem 2
v + 0.5 = -0.866025404 Simplifying v + 0.5 = -0.866025404 Reorder the terms: 0.5 + v = -0.866025404 Solving 0.5 + v = -0.866025404 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + v = -0.866025404 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + v = -0.866025404 + -0.5 v = -0.866025404 + -0.5 Combine like terms: -0.866025404 + -0.5 = -1.366025404 v = -1.366025404 Simplifying v = -1.366025404Solution
The solution to the problem is based on the solutions from the subproblems. v = {0.366025404, -1.366025404}
