If `a(p+q)^2+2bpq+c=0 and q(p+r)^2+2bpr+c=0` then (A) `qr=p^2 + c/a` (B) `qr=p^2 - c/a` (C) `q+r = 2(a+b)/a` (D) `q+r= -2(a+b)/(a)`

If quad a(p+q)^(2)+2bpq+c=0abda(p+r)^(2)+2bpr+c=0(a!=0), then qr=p^(2) b.qr=p^(2)+(c)/(a) c.qr=p^(2) d.none of these

If a,b are roots of x^2+px+q=0 and c,d are the roots x^2-px+r=0 then a^2+b^2+c^2+d^2 equals (A) p^2-q-r (B) p^2+q+r (C) p^2+q^2-r^2 (D) 2(p^2-q+r)

If a^(p)=b^(q)=c^(r) and b^(2)=ac then what is value of q(p+r)/pr]

If p:q=2:3 and q:r=4,:5, then find p:q:r.

If p:q=3:2 and q:r=6:5 then p:q:r is equal to

If p > q and r < 0 , then which is true? (a) p r < q r (b) p r < q r (c) p + r < q + r (d) None of these

Given pq + qr + rp = 0 find (p^(2))/(p^(2)-qr) + (q^(2))/(q^(2) -rp) + (r^(2))/(r^(2) - pq)= ?
