Question

(a+1)(a-1)(a²+1)is equal to (a⁴-1)

Answer 1

Answer:(a²-1)(a²+1) or = (a^4 - 1)

Step-by-step explanation:

In the LHS part

⇒(a+1)(a-1)(a²+1)

⇒(a+1)(a-1) = a²-1           [by Identity]

⇒(a²-1)(a²+1) = (a^4-1) ⇒ RHS

hence LHS = RHS

Proved

Answer 2

(a+1)(a-1) (a^2+1)

= (a^2-) (a^2+1)

= (a^4-1) Proov .it
