Simplifying (2 + v)(5v + -9) = 0 Reorder the terms: (2 + v)(-9 + 5v) = 0 Multiply (2 + v) * (-9 + 5v) (2(-9 + 5v) + v(-9 + 5v)) = 0 ((-9 * 2 + 5v * 2) + v(-9 + 5v)) = 0 ((-18 + 10v) + v(-9 + 5v)) = 0 (-18 + 10v + (-9 * v + 5v * v)) = 0 (-18 + 10v + (-9v + 5v2)) = 0 Combine like terms: 10v + -9v = 1v (-18 + 1v + 5v2) = 0 Solving -18 + 1v + 5v2 = 0 Solving for variable 'v'. Factor a trinomial. (-2 + -1v)(9 + -5v) = 0Subproblem 1
Set the factor '(-2 + -1v)' equal to zero and attempt to solve: Simplifying -2 + -1v = 0 Solving -2 + -1v = 0 Move all terms containing v to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + -1v = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -1v = 0 + 2 -1v = 0 + 2 Combine like terms: 0 + 2 = 2 -1v = 2 Divide each side by '-1'. v = -2 Simplifying v = -2Subproblem 2
Set the factor '(9 + -5v)' equal to zero and attempt to solve: Simplifying 9 + -5v = 0 Solving 9 + -5v = 0 Move all terms containing v to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -5v = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -5v = 0 + -9 -5v = 0 + -9 Combine like terms: 0 + -9 = -9 -5v = -9 Divide each side by '-5'. v = 1.8 Simplifying v = 1.8Solution
v = {-2, 1.8}
