Answer 1

Pv2q-3pqv2+8pq-18q+5p+28

Answer 2

$(18 – 3p – 11q + 5pq – 2pq2 + 5p2q) – (4p2q – 3pq + 5pq2 – 8p + 7q – 10) \\ </p><p>= 18 – 3p – 11q + 5pq – 2pq2 + 5p2q – 4p2q + 3pq – 5pq2 + 8p – 7q + 10 \\ </p><p>=18+10 -3p+8p -11q – 7q + 5 pq+ 3pq- 2pq^2 – 5pq^2 + 5 p^2 q – 4p^2 q \\ </p><p>= 28 + 5p – 18q + 8pq – 7pq2 + p2q$
