Simplifying (5v + 1)(4 + -1v) = 0 Reorder the terms: (1 + 5v)(4 + -1v) = 0 Multiply (1 + 5v) * (4 + -1v) (1(4 + -1v) + 5v * (4 + -1v)) = 0 ((4 * 1 + -1v * 1) + 5v * (4 + -1v)) = 0 ((4 + -1v) + 5v * (4 + -1v)) = 0 (4 + -1v + (4 * 5v + -1v * 5v)) = 0 (4 + -1v + (20v + -5v2)) = 0 Combine like terms: -1v + 20v = 19v (4 + 19v + -5v2) = 0 Solving 4 + 19v + -5v2 = 0 Solving for variable 'v'. Factor a trinomial. (4 + -1v)(1 + 5v) = 0Subproblem 1
Set the factor '(4 + -1v)' equal to zero and attempt to solve: Simplifying 4 + -1v = 0 Solving 4 + -1v = 0 Move all terms containing v to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1v = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1v = 0 + -4 -1v = 0 + -4 Combine like terms: 0 + -4 = -4 -1v = -4 Divide each side by '-1'. v = 4 Simplifying v = 4Subproblem 2
Set the factor '(1 + 5v)' equal to zero and attempt to solve: Simplifying 1 + 5v = 0 Solving 1 + 5v = 0 Move all terms containing v to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + 5v = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 5v = 0 + -1 5v = 0 + -1 Combine like terms: 0 + -1 = -1 5v = -1 Divide each side by '5'. v = -0.2 Simplifying v = -0.2Solution
v = {4, -0.2}
