Simplifying (v + 3)(v + -7) = 0 Reorder the terms: (3 + v)(v + -7) = 0 Reorder the terms: (3 + v)(-7 + v) = 0 Multiply (3 + v) * (-7 + v) (3(-7 + v) + v(-7 + v)) = 0 ((-7 * 3 + v * 3) + v(-7 + v)) = 0 ((-21 + 3v) + v(-7 + v)) = 0 (-21 + 3v + (-7 * v + v * v)) = 0 (-21 + 3v + (-7v + v2)) = 0 Combine like terms: 3v + -7v = -4v (-21 + -4v + v2) = 0 Solving -21 + -4v + v2 = 0 Solving for variable 'v'. Factor a trinomial. (-3 + -1v)(7 + -1v) = 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 + -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 = 7Solution
v = {-3, 7}
