Simplifying (7 + v)(3v + -4) = 0 Reorder the terms: (7 + v)(-4 + 3v) = 0 Multiply (7 + v) * (-4 + 3v) (7(-4 + 3v) + v(-4 + 3v)) = 0 ((-4 * 7 + 3v * 7) + v(-4 + 3v)) = 0 ((-28 + 21v) + v(-4 + 3v)) = 0 (-28 + 21v + (-4 * v + 3v * v)) = 0 (-28 + 21v + (-4v + 3v2)) = 0 Combine like terms: 21v + -4v = 17v (-28 + 17v + 3v2) = 0 Solving -28 + 17v + 3v2 = 0 Solving for variable 'v'. Factor a trinomial. (-7 + -1v)(4 + -3v) = 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 '(4 + -3v)' equal to zero and attempt to solve: Simplifying 4 + -3v = 0 Solving 4 + -3v = 0 Move all terms containing v to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -3v = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -3v = 0 + -4 -3v = 0 + -4 Combine like terms: 0 + -4 = -4 -3v = -4 Divide each side by '-3'. v = 1.333333333 Simplifying v = 1.333333333Solution
v = {-7, 1.333333333}
