If p,q,r are the roots of the equation ax^3 + bx^2 + cx + d = 0. then find equation whose roots area] pq,qr,prb] [pq]^2,[qr]^2,[pr]^2c] p[q+r],q[p+r],r[p+q]d] pq+1/r,qr+1/p,pr+1/qe] p-1/qr,q-1/rp,r-1/pq

Answer» If p,q,r are the roots of the equation ax^3 + bx^2 + cx + d = 0. then find equation whose roots are
a] pq,qr,pr
b] [pq]^2,[qr]^2,[pr]^2
c] p[q+r],q[p+r],r[p+q]
d] pq+1/r,qr+1/p,pr+1/q
e] p-1/qr,q-1/rp,r-1/pq
