Paper 2Logic & proofAlgebra

Given that pp and qq are real constants, which of the following is a necessary but not sufficient condition for the equation

qx+2p=x3+qx2+(p−q)x−8qx+2p=x^3+qx^2+(p-q)x-8

to have exactly one real solution?

Ap>3p>3
Bq≤−2q\le-2
C4p≥q2+4q−124p\ge q^2+4q-12
Dp>q+3p>q+3
E4p>q2+4q−124p>q^2+4q-12
Fp+q>1p+q>1
