Distributive property requires that the term - in this case (-xy)- be "distributed" within the other bracket and multiplied individually, thus:
(3x + 2y - 1)( -xy)
= 3x(-xy) + 2y(-xy) -1(-xy)
= `-3x^2y + (-2xy^2) - (-xy)`
= `-3x^2y - 2xy^2 + xy`
I am not permitted according to eNotes rules to answer multiple questions. Apply the same method to your second question, refer to the link below or post your question separately.
A) = `-3x^2y - 2xy^2 + xy`
