Subproblem 1

Set the factor 'v' equal to zero and attempt to solve: Simplifying v = 0 Solving v = 0 Move all terms containing v to the left, all other terms to the right. Simplifying v = 0

Subproblem 2

Set the factor '(-1 + -1v + v2)' equal to zero and attempt to solve: Simplifying -1 + -1v + v2 = 0 Solving -1 + -1v + v2 = 0 Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + -1v + 1 + v2 = 0 + 1 Reorder the terms: -1 + 1 + -1v + v2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1v + v2 = 0 + 1 -1v + v2 = 0 + 1 Combine like terms: 0 + 1 = 1 -1v + v2 = 1 The v term is -1v. 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. -1v + 0.25 + v2 = 1 + 0.25 Reorder the terms: 0.25 + -1v + v2 = 1 + 0.25 Combine like terms: 1 + 0.25 = 1.25 0.25 + -1v + v2 = 1.25 Factor a perfect square on the left side: (v + -0.5)(v + -0.5) = 1.25 Calculate the square root of the right side: 1.118033989 Break this problem into two subproblems by setting (v + -0.5) equal to 1.118033989 and -1.118033989.

Subproblem 1

v + -0.5 = 1.118033989 Simplifying v + -0.5 = 1.118033989 Reorder the terms: -0.5 + v = 1.118033989 Solving -0.5 + v = 1.118033989 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 = 1.118033989 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + v = 1.118033989 + 0.5 v = 1.118033989 + 0.5 Combine like terms: 1.118033989 + 0.5 = 1.618033989 v = 1.618033989 Simplifying v = 1.618033989

Subproblem 2

v + -0.5 = -1.118033989 Simplifying v + -0.5 = -1.118033989 Reorder the terms: -0.5 + v = -1.118033989 Solving -0.5 + v = -1.118033989 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 = -1.118033989 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + v = -1.118033989 + 0.5 v = -1.118033989 + 0.5 Combine like terms: -1.118033989 + 0.5 = -0.618033989 v = -0.618033989 Simplifying v = -0.618033989

Solution

The solution to the problem is based on the solutions from the subproblems. v = {1.618033989, -0.618033989}

Solution

v = {0, 1.618033989, -0.618033989}
