If px^(3)+qx^(2)+rx+s=0 is a R.E .of second type then p=s,q=r p=-s,q=-r p=s,q=-r p=-s ,q=r

If x^(4) + px^(3) + rx + s^(2) is a perfect square then ps =

If x^(4) + px^(3) + rx + s^(2) is a perfect square then p^(3) + 8r =

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 the sum of two roots of the equation x^4 +px^3 +qx^2 + rx +s=0 equals the sum of the other two ,prove that p^3 + 8r =4pq

three roots of the equation x^(4)-px^(3)+qx^(2)-rx+s=0 are tan A,tan B and tan C when A,B,C are the angle of a triangle,the fourth root of the biquadratic is -

For a cubic polynomial t(x) = px^(3) + qx^(2) + rx +s , which of the following is always true:

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