This is a problem of Difference-of-squares. We know that for a difference of squares [tex]a^2-b^2[/tex] the factorization is given by:

[tex](a-b)(a+b)[/tex]

To learn this you need to remember that a difference means subtraction. So applying those concepts we can solve this problem step by step.

Applying distributive property:

[tex](2n)(2n-2)+2(2n-2)[/tex]

Applying distributive property again:

[tex]4n^2-4n+4n+4[/tex]

Simplifying:

[tex]4n^2-4[/tex]

The correct answer is C
