Simplifying (2v + 7)(1 + v) = 0 Reorder the terms: (7 + 2v)(1 + v) = 0 Multiply (7 + 2v) * (1 + v) (7(1 + v) + 2v * (1 + v)) = 0 ((1 * 7 + v * 7) + 2v * (1 + v)) = 0 ((7 + 7v) + 2v * (1 + v)) = 0 (7 + 7v + (1 * 2v + v * 2v)) = 0 (7 + 7v + (2v + 2v2)) = 0 Combine like terms: 7v + 2v = 9v (7 + 9v + 2v2) = 0 Solving 7 + 9v + 2v2 = 0 Solving for variable 'v'. Factor a trinomial. (7 + 2v)(1 + v) = 0Subproblem 1
Set the factor '(7 + 2v)' equal to zero and attempt to solve: Simplifying 7 + 2v = 0 Solving 7 + 2v = 0 Move all terms containing v to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 2v = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 2v = 0 + -7 2v = 0 + -7 Combine like terms: 0 + -7 = -7 2v = -7 Divide each side by '2'. v = -3.5 Simplifying v = -3.5Subproblem 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 = {-3.5, -1}
