O (x-8) (x2 - 3)

O (X + 8) (x2 + 3)

O (x-8) (x2 + 3)

O (X + 8) (x2 - 3)

Option d is the answer

(X + 8) (x2 - 3)

Step-by-step explanation:

x3 + 8x2 - 3x - 24

= (X + 8) (x2 - 3)

Check all the options by expansion

(a)

(x-8) (x2 - 3)

=x3-3x-8x2+24

(b)

(X + 8) (x2 + 3)

=X3+3x+8x2-24

(c)

(x-8) (x2 + 3)

=X3+3x-8x2-24

(d)

(X + 8) (x2 - 3)

=X3-3x+8x2-24
