Step-by-step explanation:
Any integer n > 1 multiplied by 2 will be even, that is
2n ← is even
Given
n² - (n - 2)² - 2 ← expand parenthesis
= n² - (n² - 4n + 4) - 2
= n² - n² + 4n - 4 - 2 ← collect like terms
= 4n - 6 ← factor out 2 from each term
= 2(2n - 3)
Hence 2(2n - 3) ← will always be even for n > 1
