Simplifying 3v2 + -21v + -1 = 0 Reorder the terms: -1 + -21v + 3v2 = 0 Solving -1 + -21v + 3v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -0.3333333333 + -7v + v2 = 0 Move the constant term to the right: Add '0.3333333333' to each side of the equation. -0.3333333333 + -7v + 0.3333333333 + v2 = 0 + 0.3333333333 Reorder the terms: -0.3333333333 + 0.3333333333 + -7v + v2 = 0 + 0.3333333333 Combine like terms: -0.3333333333 + 0.3333333333 = 0.0000000000 0.0000000000 + -7v + v2 = 0 + 0.3333333333 -7v + v2 = 0 + 0.3333333333 Combine like terms: 0 + 0.3333333333 = 0.3333333333 -7v + v2 = 0.3333333333 The v term is -7v. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7v + 12.25 + v2 = 0.3333333333 + 12.25 Reorder the terms: 12.25 + -7v + v2 = 0.3333333333 + 12.25 Combine like terms: 0.3333333333 + 12.25 = 12.5833333333 12.25 + -7v + v2 = 12.5833333333 Factor a perfect square on the left side: (v + -3.5)(v + -3.5) = 12.5833333333 Calculate the square root of the right side: 3.547299442 Break this problem into two subproblems by setting (v + -3.5) equal to 3.547299442 and -3.547299442.Subproblem 1
v + -3.5 = 3.547299442 Simplifying v + -3.5 = 3.547299442 Reorder the terms: -3.5 + v = 3.547299442 Solving -3.5 + v = 3.547299442 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + v = 3.547299442 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + v = 3.547299442 + 3.5 v = 3.547299442 + 3.5 Combine like terms: 3.547299442 + 3.5 = 7.047299442 v = 7.047299442 Simplifying v = 7.047299442Subproblem 2
v + -3.5 = -3.547299442 Simplifying v + -3.5 = -3.547299442 Reorder the terms: -3.5 + v = -3.547299442 Solving -3.5 + v = -3.547299442 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + v = -3.547299442 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + v = -3.547299442 + 3.5 v = -3.547299442 + 3.5 Combine like terms: -3.547299442 + 3.5 = -0.047299442 v = -0.047299442 Simplifying v = -0.047299442Solution
The solution to the problem is based on the solutions from the subproblems. v = {7.047299442, -0.047299442}
