If `px ^(2)+ qx + r=0` has equal roots then value of r will be `"_______."`

If roots of ax^(2) + bx + c = 0 are 2 , more than the roots of px^(2) + qx + r = 0 , then the value of c in terms of p,q and r is

If the sum of two roots of the equation x^(3) -2px^(2)+3qx -4r=0 is zero, then the value of r is

If the equations px^(2)+qx+r=0 and rx^(2)+qx+p=0 have a negative common root then the value of (p-q+r)=

Let alpha, beta be the roots of the equation x^(2) - px + r = 0 and (alpha)/(2) , 2 beta be the roots of the equation x^(2) - qx + r = 0 . Then the value of r is :

If the roots of the quadratic equation px^(2)+qx+r=0 are reciprocal to each other ,then the relation between p and r is

find the condition that px^(3) + qx^(2) +rx +s=0 has exactly one real roots, where p ,q ,r,s,in 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 alpha , beta , gamma are the roots of the equation px^3 - qx + r = 0 , then the value of alpha + beta + gamma is
