Subproblem 1

Set the factor '(-5 + -5v + v2)' equal to zero and attempt to solve: Simplifying -5 + -5v + v2 = 0 Solving -5 + -5v + v2 = 0 Begin completing the square. Move the constant term to the right: Add '5' to each side of the equation. -5 + -5v + 5 + v2 = 0 + 5 Reorder the terms: -5 + 5 + -5v + v2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -5v + v2 = 0 + 5 -5v + v2 = 0 + 5 Combine like terms: 0 + 5 = 5 -5v + v2 = 5 The v term is -5v. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5v + 6.25 + v2 = 5 + 6.25 Reorder the terms: 6.25 + -5v + v2 = 5 + 6.25 Combine like terms: 5 + 6.25 = 11.25 6.25 + -5v + v2 = 11.25 Factor a perfect square on the left side: (v + -2.5)(v + -2.5) = 11.25 Calculate the square root of the right side: 3.354101966 Break this problem into two subproblems by setting (v + -2.5) equal to 3.354101966 and -3.354101966.

Subproblem 1

v + -2.5 = 3.354101966 Simplifying v + -2.5 = 3.354101966 Reorder the terms: -2.5 + v = 3.354101966 Solving -2.5 + v = 3.354101966 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + v = 3.354101966 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + v = 3.354101966 + 2.5 v = 3.354101966 + 2.5 Combine like terms: 3.354101966 + 2.5 = 5.854101966 v = 5.854101966 Simplifying v = 5.854101966

Subproblem 2

v + -2.5 = -3.354101966 Simplifying v + -2.5 = -3.354101966 Reorder the terms: -2.5 + v = -3.354101966 Solving -2.5 + v = -3.354101966 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + v = -3.354101966 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + v = -3.354101966 + 2.5 v = -3.354101966 + 2.5 Combine like terms: -3.354101966 + 2.5 = -0.854101966 v = -0.854101966 Simplifying v = -0.854101966
