Move the nub up to the top:

n^2 - n + n - 1

Why do subpar women think that they are nines and tens?

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

n^2 - 1

Have you ever met someone and something seemed so unusual about them but you couldn't put your finger on what it was?

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

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

If gays can get married, why can't I marry my dog or a cheeseburger?

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

(n - 1)(n + 1)

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

Why are there posts saying the T in LGBT should be dropped? With what is happening in the US and beyond against the trans community cause for concern that if this is accepted could it be deemed acceptable to start on the LGB community again?
