Respuesta :

I think it would be the first option.
Because when u factors x^2+4x-5 you get (x+5) & (x-1)
So when u write it overall it would look like:
(x+5)(x-1) / 1-x
So then i think u cancel out the x-1 and 1-x which leaves u with x+5

Im not sure tho
choixongdong
  x^2 + 4x - 5
-----------------
    1 -x

  (x -1)(x +5)
=-----------------
    -(x - 1)
= -(x+5)
= -x - 5

answer is D. last one
