    Answer:

    Step-by-step explanation:

    (x-y)³=x³-3x²y+3xy²-y³

    (4a-3)³=(4a)³-3(4a)²*-3+3(4a)*(-3)²-(-3)³

    Answer:

    given ,(4a-3)^3

    we know that (a-b)^3 = a^3 -3a^2b+ 3ab^2- b^3

    ie (4a-3)^3 = (4a)^3- 3(4a)^2(3) + 3(4a) (3)^2 – 3^3

    = 64a^3 – 9(16a^2)+ 12a(9) – 27

    =64a^3 – 144a^2 + 108a -27

    Step-by-step explanation:
