Simplifying (v + 1)(v + -4) = 0 Reorder the terms: (1 + v)(v + -4) = 0 Reorder the terms: (1 + v)(-4 + v) = 0 Multiply (1 + v) * (-4 + v) (1(-4 + v) + v(-4 + v)) = 0 ((-4 * 1 + v * 1) + v(-4 + v)) = 0 ((-4 + 1v) + v(-4 + v)) = 0 (-4 + 1v + (-4 * v + v * v)) = 0 (-4 + 1v + (-4v + v2)) = 0 Combine like terms: 1v + -4v = -3v (-4 + -3v + v2) = 0 Solving -4 + -3v + v2 = 0 Solving for variable 'v'. Factor a trinomial. (-1 + -1v)(4 + -1v) = 0Subproblem 1
Set the factor '(-1 + -1v)' equal to zero and attempt to solve: Simplifying -1 + -1v = 0 Solving -1 + -1v = 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 + -1v = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1v = 0 + 1 -1v = 0 + 1 Combine like terms: 0 + 1 = 1 -1v = 1 Divide each side by '-1'. v = -1 Simplifying v = -1Subproblem 2
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 = 4Solution
v = {-1, 4}
