[" 4.Factorize : "],[" (i) "(p^(2)+2p^(2)q)]

Factorize: 4p^2-9q^2

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

Factorize (p+q)^2-20 (p+q)-125 .

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

Factorize the expressions: 7p^2+21q^2

If AM and GM of x and y are in the ratio p: q, then x: y is : a) p - sqrt(p^(2)+ q^(2)) : p +sqrt (p^(2)+ q^(2)) b) p +sqrt(p^(2) - q^ (2) ) : p- sqrt(p^(2)-q^(2)) c) p : q d) p + sqrt(p^(2) + q^(2)) : p-sqrt(p^(2) + q^(2))

Show that the sequence (p + q)^(2), (p^(2) + q^(2)), (p-q)^(2) … is an A.P.

Show that the sequence (p + q)^(2), (p^(2) + q^(2)), (p-q)^(2) … is an A.P.
