if p^(2)+2q^(2)+5r^(2)+2pq-4qr+6p+6q-2r+10le0 for p,q,r in R then identify correct option?

if p^(2)+2q^(2)+5r^(2)+2pq-4qr+6p+6q-2r+10le0 for p,q,r in R then identify correct option?

Factoris the expression. 63 p ^(2) q ^(2) r ^(2) s -9pq ^(2) r ^(2) s ^(2) + 15 p ^(2) qr ^(2) s ^(2) - 60 p ^(2) q ^(2) rs ^(2)

If p = 4, q= 3 and r = -2, find the values of : (p^(2)+q^(2)-r^(2))/(pq+qr-pr)

(3p^(2)qr^(3)) xx (- 4p^(3)q^(2)r^(2))xx (7pq^(2)r) is equal to

if p,q,r be real then the interval in which f(x) =|underset(pr" "qr" "x+r^(2))underset(pq" "x+q^(2)" "qr)(x+p^(2)" "pq" "pr)|,

If Delta=|[0,q,r],[q,r,p],[r,p,q]|, then |[rq-p^(2),pr-q^(2),pq-r^(2)],[rp-q^(2),pq-r^(2),rq-p^(2)],[pq-r^(2),rq-p^(2),pr-q^(2)]| is equal to

If (p^(2)+q^(2)), (pq+qr), (q^(2)+r^(2)) are in GP then prove that p, q, r are in GP.

If p, q, r, s are in G.P, show that (p^2 + q^2 + r^2) (q^2 + r^2 + s^2) = (pq + qr + rs)^2
