The trinomial x2 – 3x – 4 is represented by the model.What are the factors of the trinomial?(x + 1) and (x – 4)(x + 4) and (x – 1)(x + 5) and (x – 4)(x + 4) and (x – 5)

for [tex]ax^2+bx+c[/tex]
if a=1 then we can factor it into (x+r)(x+t) where rt=c and r+t=b

given
[tex]1x^2-3x-4[/tex]
what 2 numbers multiply to get -4 and add to get -3?
-4 and 1

(x+1)(x-4)
answer is the first option
