LET ME TAKE THE ROOTS AS m,n,o,p .................
ax4+bx3+cx2+dx+e = a(x-m ) ( x-n ) (x-o) ( x-p)
put x= i [iota]
u will get, a [m-i] [n-i] [o-i] [p-i] = a-bi-c+di+e
[.........infact u get[i-m] but multiply each with -1.]
put x= -i
u will get a [m+i] [n+i] [o+i] [p+i] = a+bi-c-di+e
now multiply both eqns.
u will get, answer.................... rate me...........and soory, it didnt knock my head off my neck
