    4x + 3xy

    = x(3y + 4)

    2ab + 3abc - 5abd

    = ab(3c - 5d + 2)

    5rst + 3st - 2rt

    = t(5rs + 3s - 2r)

    For 4x + 3xy,

    Since you identified that x is its common factor, the answer is x(4 + 3y)

    For 2ab + 3abc - 5abd,

    Since you identified that ab is its common factor, the answer is ab(2 + 3c + 5d)

    For 5rst + 3st - 2rt,

    Since you identified that t is its common factor, the answer is t (5rs + 3s - 2r)

    Hope this helped!
