Question

from the sum 2p^2q^2-3pq+4,5+7pq-3p^2q^2 subtract 9p^2q^2+5pq+11​

Answer 1

2p^2 x q^2 - 3pq + 4 + 5 + 7pq - 3p^2 x q^2

= 2p^2 x q^2 - 3p^2 x q^2 + 7pq - 3pq + 4 + 5

= -p^2 x q^2 + 4pq + 9

= -p^2 x q^2 + 4pq + 9 - 9p^2 q^2 - 5pq - 11

= -10p^2 x q^2 -4pq -2

= -2(5p^2q^2 + 2pq + 1) ANSWER .
