If `px^(3)+qx^(2)+rx+s=0` is a R.E .of second type then
p=s,q=r
p=-s,q=-r
p=s,q=-r
p=-s ,q=r

find the condition that px^(3) + qx^(2) +rx +s=0 has exactly one real roots, where p ,q ,r,s,in R

If S(p,q,r)=(~p)vv(~(q ^^ r)) is a compound statement, then S(~p,~q,~r) is

If p : q :r :s = 3 : 4 : 7 : 8 and p+s=55 , then find q + r.

p,q,r,s in R,x^(2)+px+q=0,x^(2)+rx+s=0 such that 2(q+s)=pr then

If (x+2) is a common factor of (px^(2)+qx+r) and (qx^(2)+px+r) then a p=q or p+q+r=0 b p=r or p+q+r=0 c) q=r or p+q+r=0 d p=q=-(1)/(2)r

If p^(th),q^(th),r^(th) and s^(th) terms of an A.P.are in G.P.then show that (p-q),(q-r),(r-s) are also in G.P.

If px^(3)+qx^(2)+rx+s is exactly divisible by x^(2)-1 , then which of the following is /are necessarily true ? (A) p = r )B) q = s (C ) p =- r (D) q =- s

If p^(a)=q^(b)=r^(c)=s^(d) and p,q,r,s are in G.P then a,b,c,d are in
