If the roots of the equation `q^2 x^2 + p^2 x + r^2 =0` are the squares of the roots of the equation `qx^2 + px + r=0` , then p,q,r are in ………………….. .

If the roots of the equation q^(2)x^(2)+p^(2)x+r^(2)=0 are the squares of the roots of the equation qx^(2)+px+r=0 , are the squares of the roots of the equation qx^(2)+px+r=0 , then q, p, r are in:

If p and q are the roots of the equation x^(2)+px+q=0 , then

If sec alpha" and cosec "alpha are the roots of the equation x^(2)-px+q=0 , then

alpha,beta be the roots of the equation x^2-px+r=0 and alpha/2 , 2beta be the roots of the equation x^2-qx+r=0 then value of r is

The roots of the eqaution (q-r)x^(2)+(r-p)x+(p-q)=0 are

If p is real, discuss the nature of the roots of the equation 4x^2+4px+p+2=0 , in terms of p.
