    -4,-5

    Step-by-step explanation:

    first set the equation equal to 0, v^2+9v+20, factor v^2+4v+5v+20, v (v+4) 5 (v+4), so the 2 factors are (v+5) and (v+4), set both equal to that 0. v+5=0 v=-5 and v+4=0 v=-4, so the answer is - 4 and - 5

    v = (-4, - 5)

    Step-by-step explanation:

    v2 + 9v + 13 = - 7

    v2 + 9v + 20 = 0

    (v + 4) (v + 5) = 0

    v = (-4, - 5)
