Simplifying v2 + -18v + 27 = 0 Reorder the terms: 27 + -18v + v2 = 0 Solving 27 + -18v + v2 = 0 Solving for variable 'v'. Begin completing the square. Move the constant term to the right: Add '-27' to each side of the equation. 27 + -18v + -27 + v2 = 0 + -27 Reorder the terms: 27 + -27 + -18v + v2 = 0 + -27 Combine like terms: 27 + -27 = 0 0 + -18v + v2 = 0 + -27 -18v + v2 = 0 + -27 Combine like terms: 0 + -27 = -27 -18v + v2 = -27 The v term is -18v. Take half its coefficient (-9). Square it (81) and add it to both sides. Add '81' to each side of the equation. -18v + 81 + v2 = -27 + 81 Reorder the terms: 81 + -18v + v2 = -27 + 81 Combine like terms: -27 + 81 = 54 81 + -18v + v2 = 54 Factor a perfect square on the left side: (v + -9)(v + -9) = 54 Calculate the square root of the right side: 7.348469228 Break this problem into two subproblems by setting (v + -9) equal to 7.348469228 and -7.348469228.Subproblem 1
v + -9 = 7.348469228 Simplifying v + -9 = 7.348469228 Reorder the terms: -9 + v = 7.348469228 Solving -9 + v = 7.348469228 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + v = 7.348469228 + 9 Combine like terms: -9 + 9 = 0 0 + v = 7.348469228 + 9 v = 7.348469228 + 9 Combine like terms: 7.348469228 + 9 = 16.348469228 v = 16.348469228 Simplifying v = 16.348469228Subproblem 2
v + -9 = -7.348469228 Simplifying v + -9 = -7.348469228 Reorder the terms: -9 + v = -7.348469228 Solving -9 + v = -7.348469228 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + v = -7.348469228 + 9 Combine like terms: -9 + 9 = 0 0 + v = -7.348469228 + 9 v = -7.348469228 + 9 Combine like terms: -7.348469228 + 9 = 1.651530772 v = 1.651530772 Simplifying v = 1.651530772Solution
The solution to the problem is based on the solutions from the subproblems. v = {16.348469228, 1.651530772}
