Simplifying (7 + -1v)(2v + 3) = 0 Reorder the terms: (7 + -1v)(3 + 2v) = 0 Multiply (7 + -1v) * (3 + 2v) (7(3 + 2v) + -1v * (3 + 2v)) = 0 ((3 * 7 + 2v * 7) + -1v * (3 + 2v)) = 0 ((21 + 14v) + -1v * (3 + 2v)) = 0 (21 + 14v + (3 * -1v + 2v * -1v)) = 0 (21 + 14v + (-3v + -2v2)) = 0 Combine like terms: 14v + -3v = 11v (21 + 11v + -2v2) = 0 Solving 21 + 11v + -2v2 = 0 Solving for variable 'v'. Factor a trinomial. (7 + -1v)(3 + 2v) = 0Subproblem 1
Set the factor '(7 + -1v)' equal to zero and attempt to solve: Simplifying 7 + -1v = 0 Solving 7 + -1v = 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 + -1v = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1v = 0 + -7 -1v = 0 + -7 Combine like terms: 0 + -7 = -7 -1v = -7 Divide each side by '-1'. v = 7 Simplifying v = 7Subproblem 2
Set the factor '(3 + 2v)' equal to zero and attempt to solve: Simplifying 3 + 2v = 0 Solving 3 + 2v = 0 Move all terms containing v to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + 2v = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 2v = 0 + -3 2v = 0 + -3 Combine like terms: 0 + -3 = -3 2v = -3 Divide each side by '2'. v = -1.5 Simplifying v = -1.5Solution
v = {7, -1.5}
