Answer 2

Answer:

Answer :- -2pqr + 4pq - 5p²qr + 2p

Step-by-step explanation:

Let the number be x.

then,

4pq - 5p²qr + 9p - x = 2pqr + 7p​

- x = 2pqr + 7p - 4pq + 5p²qr - 9p

- x = 2pqr - 4pq + 5p²qr + 7p - 9p

- x = 2pqr - 4pq + 5p²qr - 2p

 x = - ( 2pqr - 4pq + 5p²qr - 2p )

 x =  - 2pqr + 4pq - 5p²qr + 2p

hence, - 2pqr + 4pq - 5p²qr + 2p should be subtracted from 4pq - 5p²qr + 9p to get 2pqr + 7p​
