    I think you mean 2 can be on only side A, 1 on only side B

    And there will be 4 on each side.

    As 2 can be only on side B, we have to select 2 more for this side out of 5

    This can be done in 5C2 ways = 10 ways

    4 on side A can be arranged in 4! Ways = 24

    4 on side B can be arranged in 4! Ways = 24

    Hence total number of arrangements = 10 times 24 times 24

    = 5760
