Simplifying v2 + -2v + -13 = -2 Reorder the terms: -13 + -2v + v2 = -2 Solving -13 + -2v + v2 = -2 Solving for variable 'v'. Reorder the terms: -13 + 2 + -2v + v2 = -2 + 2 Combine like terms: -13 + 2 = -11 -11 + -2v + v2 = -2 + 2 Combine like terms: -2 + 2 = 0 -11 + -2v + v2 = 0 Begin completing the square. Move the constant term to the right: Add '11' to each side of the equation. -11 + -2v + 11 + v2 = 0 + 11 Reorder the terms: -11 + 11 + -2v + v2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + -2v + v2 = 0 + 11 -2v + v2 = 0 + 11 Combine like terms: 0 + 11 = 11 -2v + v2 = 11 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 = 11 + 1 Reorder the terms: 1 + -2v + v2 = 11 + 1 Combine like terms: 11 + 1 = 12 1 + -2v + v2 = 12 Factor a perfect square on the left side: (v + -1)(v + -1) = 12 Calculate the square root of the right side: 3.464101615 Break this problem into two subproblems by setting (v + -1) equal to 3.464101615 and -3.464101615.Subproblem 1
v + -1 = 3.464101615 Simplifying v + -1 = 3.464101615 Reorder the terms: -1 + v = 3.464101615 Solving -1 + v = 3.464101615 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 = 3.464101615 + 1 Combine like terms: -1 + 1 = 0 0 + v = 3.464101615 + 1 v = 3.464101615 + 1 Combine like terms: 3.464101615 + 1 = 4.464101615 v = 4.464101615 Simplifying v = 4.464101615Subproblem 2
v + -1 = -3.464101615 Simplifying v + -1 = -3.464101615 Reorder the terms: -1 + v = -3.464101615 Solving -1 + v = -3.464101615 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 = -3.464101615 + 1 Combine like terms: -1 + 1 = 0 0 + v = -3.464101615 + 1 v = -3.464101615 + 1 Combine like terms: -3.464101615 + 1 = -2.464101615 v = -2.464101615 Simplifying v = -2.464101615Solution
The solution to the problem is based on the solutions from the subproblems. v = {4.464101615, -2.464101615}
