Question

Q # 6 please multiply help

Answer 1

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


`(a-b)(a+b)`

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:


`(2n)(2n-2)+2(2n-2)`

Applying distributive property again:


`4n^2-4n+4n+4`

Simplifying:


`4n^2-4`

The correct answer is C
