If p and q are positive then the roots of the equation `x^2-px-q = 0` are- (A) imaginary (C) real & both negative (B) real & of opposite sign

If p, q, r are positive and are in AP, the roots of quadratic equation px^(2) + qx + r = 0 are real for :

IF the roots of the equation px^2-2qx+p=0 are real and unequal, show that the roots of the equation qx^2-2px+q=0 are imaginary (both p and q are real).

if P , q, r are positive and are in A.P the roots of the quadrativ px^2 + qx + r=0 real for

Show that the roots of the equation x^(2)+px-q^(2)=0 are real for all real values of p and q.

If p,q,r are in A.P. and are positive, the roots of the quadratic equation px^(2) + qx + r = 0 are real for :

If p, q, are real and p ne q then the roots of the equation (p-q) x^(2)+5(p+q) x-2(p-q)=0 are
