Simplifying (3 + -1v)(3v + 7) = 0 Reorder the terms: (3 + -1v)(7 + 3v) = 0 Multiply (3 + -1v) * (7 + 3v) (3(7 + 3v) + -1v * (7 + 3v)) = 0 ((7 * 3 + 3v * 3) + -1v * (7 + 3v)) = 0 ((21 + 9v) + -1v * (7 + 3v)) = 0 (21 + 9v + (7 * -1v + 3v * -1v)) = 0 (21 + 9v + (-7v + -3v2)) = 0 Combine like terms: 9v + -7v = 2v (21 + 2v + -3v2) = 0 Solving 21 + 2v + -3v2 = 0 Solving for variable 'v'. Factor a trinomial. (3 + -1v)(7 + 3v) = 0Subproblem 1
Set the factor '(3 + -1v)' equal to zero and attempt to solve: Simplifying 3 + -1v = 0 Solving 3 + -1v = 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 + -1v = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1v = 0 + -3 -1v = 0 + -3 Combine like terms: 0 + -3 = -3 -1v = -3 Divide each side by '-1'. v = 3 Simplifying v = 3Subproblem 2
Set the factor '(7 + 3v)' equal to zero and attempt to solve: Simplifying 7 + 3v = 0 Solving 7 + 3v = 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 + 3v = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 3v = 0 + -7 3v = 0 + -7 Combine like terms: 0 + -7 = -7 3v = -7 Divide each side by '3'. v = -2.333333333 Simplifying v = -2.333333333Solution
v = {3, -2.333333333}
