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

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

Move the nub up to the top:

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

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

This is a real question: Why do a lot of men/boys hate (yes, hate) women that voice their criteria in choosing a partner? Even when the criteria is sane and responsible. Besides it being, sadly, an effective mating strategy, why does it exist?

Did you become a cuckold for your wife?

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

Why does Christianity push reconciliation after a partner cheats? Mine had a 7-year affair with someone half my age. He cheated and lied. He is not the same to me.

n^2 - n + n - 1

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

What does it mean if someone asks if it’s pink?

n^2 - 1

(n - 1)(n + 1)

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

Is anyone else losing complete respect for the US at this point?
