The Answer of Multiply.
-$(a-b)\left(a^{2}-a b-9 b^{2}\right)$
A) $a^{3}-8 a^{2} b+9 b^{3}$
B) $a^{3}-2 a^{2} b-8 a b^{2}+9 b^{3}$
C) $a^{3}-2 a^{2} b-10 a b^{2}-9 b^{3}$
D) $a^{3}-2 a^{2} b-9 a b^{2}+9 b^{3}$

Multiply - (a−b)(a2−ab−9b2)(a-b)\left(a^{2}-a b-9 b^{2}\right)(a−b)(a2−ab−9b2) A) a3−8a2b+9b3a^{3}-8 a^{2} b+9 b^{3}a3−8a2b+9b3 B) a3−2a2b−8ab2+9b3a^{3}-2 a^{2} b-8 a b^{2}+9 b^{3}a3−2a2b−8ab2+9b3

Multiply
- $(a-b)\left(a^{2}-a b-9 b^{2}\right)$ A) $a^{3}-8 a^{2} b+9 b^{3}$ B) $a^{3}-2 a^{2} b-8 a b^{2}+9 b^{3}$
