Question

find the continued product: (x-1)(x+1)(x²+1)​

Answer 1

Answer:

x⁴ - 1

Step-by-step explanation:

using identity a² - b² = a+b × a-b 2 times

Answer 2

Step-by-step explanation:

suitable identity : [(a+b)(a-b)=a²-b²]

(x-1)(x+1)(x²+1)

=(x²-1²)(x²+1)

=(x²-1)(x²+1)

=(x²)²-(1)²

=x⁴-1
