Question

please answer the following link

Answer 1

let alpha be 'a' and beta 'b'.

a+b=-(b/a)=-(-p/1)
=p
a*b=c/a=q/1
=q

a^4+b^4/a^2b^2=(a^2+b^2)^2-2a^2b^2/
(ab)(ab)
=(a^2+b^2)^2-2(ab)(ab)/q*q
=(a^2+b^2)^2-2q^2/q^2
=[(a+b)^2]^2-2ab-2q^2/q^2
=p^4-2q-2q^2/q^2
=p^4/q^2-2q/q^2-2q^2/q^2
=>p^4/q^2-2/q-2
