Step-by-step explanation:
(a+1/a)(a-1/a)(a²+1/a²)(a⁴+1/a⁴)
=[(a+1/a)(a-1/a)](a²+1/a²)(a⁴+1/a⁴)
=[a²-(1/a)²](a²+1/a²)(a⁴+1/a⁴)
=[(a²-1/a²)(a²+1/a²)](a⁴+1/a⁴)
= [(a²)²-(1/a²)²](a⁴+1/a⁴)
= (a⁴-1/a⁴)(a⁴+1/a⁴)
= (a⁴)²-(1/a⁴)²

a=(-1) is your answer.
Step-by-step explanation:
a²+a+a+1
a²+2a+1
If you need to factorise this =》
a²+1a+1a+1=0
a(a+1)+1(a+1)=0
(a+1)(a+1)=0
a+1=0
a=(-1)
Hope this helps you!
