Question

Plsssssssss answer mates..........

Answer 1

The answer is option 3.

a2-b2=(a+b)(a-b)

if you apply it you will get answer as

(n2-2)(n2+2)

If you expand it further you will get the answer

Answer 2

Given Equation is n^2 - 4.

⇒ (n^2)^2 - (2)^2

We know that a^2 - b^2 = (a + b)(a - b)

⇒ (n^2 + 2)(n^2 - 2)

⇒ (n^2 + 2)((n)^2 - (√2)^2)

⇒ (n^2 + 2)(n + √2)(n - √2)

Therefore, the answer is Option (3).

Hope it helps!
