Question

(a+1)(a-1)(a2+1)=??​

Answer 1

Answer:

a⁴ - 1 is your correct answer.....

Step by step solution:

(a+1) (a-1) (a²+1)

[a(a-1)+1(a-1)] (a²+1)

(a² - a + a - 1) (a²+1)

(a² - 1) (a²+1)

( a²) ² - (1) ²                .............[1]

[ since, (a+b) (a-b) = (a) ²- (b²) ]

a⁴-1                             .......from [1]
