Question

( A+1)(A-1)(A 4-1) can be simplyfief
as. what is the answer​

Answer 1

the first identity for algebra

( A + B )² = a² + 2ab + b²

Answer 2

Step-by-step explanation:

Simplifying the given expression,

(a+1)(a−1)(a2+1)=[(a+1)(a−1)]×(a2+1)

=(a2−12)×(a2+1)[Using the identity (x+y)(x−y)=x2−y2]

=(a2−1)(a2+1)

=(a2)2−1[Using the identity (x+y)(x−y)=x2−y2]

=a4−1
