Why is (n-1)(n+1)=n^2-1?

Move the nub up to the top:

I committed the unpardonable sin. God immediately punished me so that I can no longer think like before and my brain is as if paralyzed and does not work. I've tried everything (confession, repentance, etc.) nothing helps. Any advice?

n^2 - n + n - 1

And you are left with almost a square. One less than the square of side n.

n^2 - 1

What do dreams about dead people mean?

The more direct answer is to look at a rectangle with sides of n + 1 and n - 1, let’s go with n = 2

So, that’s a rectangle with sides 2 and 4.

Why does it itch on my vulva, uterus, and sides of my vagina, but it doesn't itch inside the vagina?

If you cut off the end of that rectangle, you make it smaller, 2 * 3 and a separate nub of size 1 * 2

The basic answer is that you cross-multiply the values in each factor:

Why do people hate on Serena (anime character)? What did she ever do to anyone except be a good friend to Ash Ketchum and an awesome trainer herself?

(n - 1)(n + 1)

How do individuals become targeted individuals? Is it solely due to experiencing stalking or harassment, or are there other factors involved?
