निम्न बहुपदों के गुणनखण्ड कीजिए - `(p+q+r)^(2)+x(p+q+r)-y(p+q+r)`

x^(p-q).x^(q-r).x^(r-p)

Add: p ( p – q), q ( q – r) and r ( r – p)

If p, q, r are in A.P the p^(2) (q + r), q^(2) (r + p), r^(2) (p+q) are in

Add: p(p-q),q(q-r) and r(r-p)

Add : p(p-q),q(q-r) and (r-p)

The roots of the equation " "(q-r)x^(2)+(r-p)x+(p-q)=0 are :a) (r-p)(q-r), 1 b) (p-q)/(q-r), 1 c) (p-r)/(q-r), 2 d) (q-r)/(p-q), 2

If p,q,r are in A.P the p^(2)(q+r),q^(2)(r+p),r^(2)(p+q) are in

Add p(p-q),q(q-r) and r(r-p)
