Simplifying (4v + 9)(1 + v) = 0 Reorder the terms: (9 + 4v)(1 + v) = 0 Multiply (9 + 4v) * (1 + v) (9(1 + v) + 4v * (1 + v)) = 0 ((1 * 9 + v * 9) + 4v * (1 + v)) = 0 ((9 + 9v) + 4v * (1 + v)) = 0 (9 + 9v + (1 * 4v + v * 4v)) = 0 (9 + 9v + (4v + 4v2)) = 0 Combine like terms: 9v + 4v = 13v (9 + 13v + 4v2) = 0 Solving 9 + 13v + 4v2 = 0 Solving for variable 'v'. Factor a trinomial. (9 + 4v)(1 + v) = 0Subproblem 1
Set the factor '(9 + 4v)' equal to zero and attempt to solve: Simplifying 9 + 4v = 0 Solving 9 + 4v = 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 + 4v = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 4v = 0 + -9 4v = 0 + -9 Combine like terms: 0 + -9 = -9 4v = -9 Divide each side by '4'. v = -2.25 Simplifying v = -2.25Subproblem 2
Set the factor '(1 + v)' equal to zero and attempt to solve: Simplifying 1 + v = 0 Solving 1 + v = 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 + v = 0 + -1 Combine like terms: 1 + -1 = 0 0 + v = 0 + -1 v = 0 + -1 Combine like terms: 0 + -1 = -1 v = -1 Simplifying v = -1Solution
v = {-2.25, -1}
