8p(2p-7q) - 7p(3q+7p)
= 16p^2 - 56pq - 21pq - 49p^2
= - 33p^2 - 77pq
= - 11p(3p - 7q)....
= 16p^2 - 56pq - 21pq - 49p^2
= - 33p^2 - 77pq
= - 11p(3p - 7q)....

7p(3q+7p) from 8p(2p-7q)
7p(3q+7p)=21pq+49p^2
8p(2p-7q)=16p^2-56pq. (21pq+49p^2) - ( 16p^2-56pq)
(21pq+49p^2)-16p^2+56pq
21pq+56pq+49p^2-16p^2
77pq+33p^2=0
7p(3q+7p)=21pq+49p^2
8p(2p-7q)=16p^2-56pq. (21pq+49p^2) - ( 16p^2-56pq)
(21pq+49p^2)-16p^2+56pq
21pq+56pq+49p^2-16p^2
77pq+33p^2=0
right
