x3 − 8x2 − 11x + 20
x3 − x2 + 22x + 40
x3 + x2 − 22x − 40
x3 + 8x2 + 11x − 20

Respuesta :

Answer:

The last choice.

Step-by-step explanation:

The  last term is  - 20 and because we have a coefficient of 1 on the x^3,  and in order to get this last term  and the given roots the factors have to be

(x  + 5)(x + 4)(x - 1)  so it is the last option.
