Q6: How much should 2p - 5pq + 7q'- 9 be increased to get 5p2-2pq +
7p ?​

Answer 1

Answer:

firstly you have to subtract 2p- 5pq+7q-9 from

5p²-2pq +7p

so,

» 5p²-2pq +7p - (2p- 5pq+7q-9)

» 5p²-2pq +7p -2p+5pq-7q+9

» 5p²-2pq+5pq+7p-2p-7q+9

» 5p²+3pq+5p-7q+9

therefore mate 5p²+3pq+5p-7q+9 is the no• which can be added to 2p- 5pq+7q-9 to get 5p²-2pq +7p
