If (alpha)/(beta) and (beta)/(alpha) are the real roots of px^(2)+qx+r=0 then (A)p=r(B)q^(2)=pq (C) q^(2)=2pr(D) none of these

If alpha and beta are roots of x^(2)+21x+4=0 and (sqrt(alpha))/(beta),(sqrt(beta))/(alpha), are roots of px^(2)+qx+2=0 then value of alpha(26p+q)

19If alpha,beta are the roots of ax^(2)+bx+c=0 and alpha+k,beta+k are the roots of px^(2)+qx+r=0. then

If alpha , beta , gamma are the roots of x^3 +px^2 +qx +r=0 then find sum alpha^2

If alpha , beta , gamma are the roots of x^3 +px^2 +qx +r=0 then find sum alpha^2

If alpha , beta , gamma are the roots of x^3 +px^2 +qx +r=0 then find sum alpha^3

If alpha , beta , gamma are the roots of x^3 +px^2 +qx +r=0 then find sum alpha^3

If alpha,beta are the roots of x^(2)-px+r=0 and alpha+1,beta-1 are the roots of x^(2)-qx+r=0 ,then r is
