Factorize `1-2pq-(p^(2)+q^(2))`

Common factor of 11 pq ^(2); 121 p ^(2) q ^(3) and 1331 p ^(2) q

Given that p = -3 and q = 2, evaluate p^(2)+(-pq^(2))-p^(2)q^(2) .

(p-q)^(2)+4pq

sin alpha =(2pq)/(p^2+q^2) => sec alpha - tan alpha= .......... A) (p-q)/(p+q) B) (pq)/(p^(2) +q^(2)) C) (p+q)/(p-q) D) (pq)/(P+q)

Factorise (Using factor theorem ) : p^(3)-3pq^(2)+2q^(3)
