Question

expand the following (3a-2b) ^3

Answer 1

Answer:

(3a)^3+(2b)^3-3×3a×2b (3a-2b)

27a^3+8b^3-54a^2b+24ab^2 is the answer

Answer 2

Answer:

$(3a - 2b)^{ 3} \\ {3a}^{3} - {2b}^{3} - 3 \times 3a \times 2b(3a - 2b) \\ 27 {a}^{3} - {8b}^{3} - 18ab(3a - 2b) \\ 27 {a}^{3} - {8b}^{3} - 54 {a}^{2} b + 36a {b}^{2}$
