I want step by step answer for this question please​

Answer 1

Answer:

((−3p)(q))((−15p³)(q²)−q³)

=((−3p)(q))((−15p³)(q²)+−q³)

=((−3p)(q))((−15p³)(q2))+((−3p)(q))(−q³)

=45p4q3+3pq4((−3p)(q))((−15p3)(q2)−q3)

=((−3p)(q))((−15p3)(q2)+−q3)

=((−3p)(q))((−15p3)(q2))+((−3p)(q))(−q3)

=45p^4q³+3pq^4
