Subproblem 1

Set the factor 'v2' equal to zero and attempt to solve: Simplifying v2 = 0 Solving v2 = 0 Move all terms containing b to the left, all other terms to the right. Add '-1v2' to each side of the equation. v2 + -1v2 = 0 + -1v2 Remove the zero: 0 = -1v2 Simplifying 0 = -1v2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(-5b + -4v)' equal to zero and attempt to solve: Simplifying -5b + -4v = 0 Solving -5b + -4v = 0 Move all terms containing b to the left, all other terms to the right. Add '4v' to each side of the equation. -5b + -4v + 4v = 0 + 4v Combine like terms: -4v + 4v = 0 -5b + 0 = 0 + 4v -5b = 0 + 4v Remove the zero: -5b = 4v Divide each side by '-5'. b = -0.8v Simplifying b = -0.8v

Subproblem 3

Set the factor '(b + -2v)' equal to zero and attempt to solve: Simplifying b + -2v = 0 Solving b + -2v = 0 Move all terms containing b to the left, all other terms to the right. Add '2v' to each side of the equation. b + -2v + 2v = 0 + 2v Combine like terms: -2v + 2v = 0 b + 0 = 0 + 2v b = 0 + 2v Remove the zero: b = 2v Simplifying b = 2v

Solution

b = {-0.8v, 2v}
