If the roots of the equation `px^(2)+qx+r=0` are in the ratio `l:m` then

The ratio of the roots of the equation ax ^2 + bx +c=0 is same as the ratio of the roots of the equation px^2 + qx +r=0 . If D_1 and D_2 are the discrimination of ax ^2 + bx + c=0 and px^2 +qx +r =0 respectively , then D_1 :D_2 =

If one of the roots of the equation px^(2)+qx+r=0 is three times the other, then which one of the following relations is correct ?

The ratio of the roots of the equation ax^2+ bx+c =0 is same as the ratio of roots of equation px^2+ qx + r =0 . If D_1 and D_2 are the discriminants of ax^2+bx +C= 0 and px^2+qx+r=0 respectively, then D_1 : D_2

If the roots of the equation ax^(2)+bx+c=0 are the reciprocals of the roots of the equation px^(2)+qx+r=0 then

If alpha,beta are the roots of the equation px^(2)-qx+r=0, then the cquation whose roots are alpha^(2)+(r)/(p) and beta^(2)+(r)/(p) is

If alpha,beta are the roots of the equation px^(2)-qx+r=0, then the equation whose roots are alpha^(2)+(r)/(p) and beta^(2)+(r)/(p) is (i) p^(3)x^(2)+pq^(2)x+r=0 (ii) px^(2)-qx+r=0 (iii) p^(3)x^(2)-pq^(2)x+q^(2)r=0 (iv) px^(2)+qx-r=0

If the roots of the equation x^(3) - px^(2) + qx - r = 0 are in A.P., then
