A) (x – 2)2(x + 1)
B) (x2+ 1)(x – 4)
C) (x + 2)(x – 2)(x + 1)
D) (x + 2)2(x + 1)

Respuesta :

Answer: C) (x+2)(x-2)(x+1)

Step-by-step explanation:

- Split the equation

x3+x2 | -4x-4

- Find the GCF of each side

x2(x+1) -4(x+1)

(x2-4)(x+1)

- (x2-4) can be split

(x+2)(x-2)(x+1)

(x+2) (x-2) (x+1) (x-1)
