Simplifying 9v2 + 18v + -65 = 0 Reorder the terms: -65 + 18v + 9v2 = 0 Solving -65 + 18v + 9v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 9 the coefficient of the squared term: Divide each side by '9'. -7.222222222 + 2v + v2 = 0 Move the constant term to the right: Add '7.222222222' to each side of the equation. -7.222222222 + 2v + 7.222222222 + v2 = 0 + 7.222222222 Reorder the terms: -7.222222222 + 7.222222222 + 2v + v2 = 0 + 7.222222222 Combine like terms: -7.222222222 + 7.222222222 = 0.000000000 0.000000000 + 2v + v2 = 0 + 7.222222222 2v + v2 = 0 + 7.222222222 Combine like terms: 0 + 7.222222222 = 7.222222222 2v + v2 = 7.222222222 The v term is 2v. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2v + 1 + v2 = 7.222222222 + 1 Reorder the terms: 1 + 2v + v2 = 7.222222222 + 1 Combine like terms: 7.222222222 + 1 = 8.222222222 1 + 2v + v2 = 8.222222222 Factor a perfect square on the left side: (v + 1)(v + 1) = 8.222222222 Calculate the square root of the right side: 2.867441756 Break this problem into two subproblems by setting (v + 1) equal to 2.867441756 and -2.867441756.Subproblem 1
v + 1 = 2.867441756 Simplifying v + 1 = 2.867441756 Reorder the terms: 1 + v = 2.867441756 Solving 1 + v = 2.867441756 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + v = 2.867441756 + -1 Combine like terms: 1 + -1 = 0 0 + v = 2.867441756 + -1 v = 2.867441756 + -1 Combine like terms: 2.867441756 + -1 = 1.867441756 v = 1.867441756 Simplifying v = 1.867441756Subproblem 2
v + 1 = -2.867441756 Simplifying v + 1 = -2.867441756 Reorder the terms: 1 + v = -2.867441756 Solving 1 + v = -2.867441756 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + v = -2.867441756 + -1 Combine like terms: 1 + -1 = 0 0 + v = -2.867441756 + -1 v = -2.867441756 + -1 Combine like terms: -2.867441756 + -1 = -3.867441756 v = -3.867441756 Simplifying v = -3.867441756Solution
The solution to the problem is based on the solutions from the subproblems. v = {1.867441756, -3.867441756}
