The condition for f(x) =x^3+px^2+qx+r^',x in R) to have no extreme value , is

The condition f(x) = x^(3)+px^(2)+qx+r (x in R) to have no extreme value is

The condition f(x)=x^3 + px^2 + qx +r ( x in R) to have no extreme value is

If zeros of x^(3)-3px^(2)+qx-r are in A.P. then

The condition that the x^(3) -px^(2) + qx -r = 0 may be the sum of the other two roots is zero =

The condition that the roots of x^(3) + 3px^(2) + 3qx + r = 0 may be in G.P 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
