If the sum of the two roots of x^(3)+px^(2)+ax+r=0 is zero then pq=

If the sum of the two roots of x^3 + px^2 + ax + r = 0 is zero then pq=

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 sum of two roots of the equation x^3-px^2 + qx-r =0 is zero, then:

If the sum of two roots of the equation x^(3)-px^(2)+q-r=0 is zero,then: (A) pq=r(B) pr =q (C) qr=p (D) None of these

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

If the roots of the equation x^(3) - px^(2) + qx - r = 0 are in A.P., then prove that, 2p^3 −9pq+27r=0

If (a)/(k),a, ak are the roots of x^(3)-px^(2)+qx-r=0 then a=
