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

Hello I am 17 year old boy and I am interested in transgender why?
And you are left with almost a square. One less than the square of side n.
So, that’s a rectangle with sides 2 and 4.
The basic answer is that you cross-multiply the values in each factor:
How many boxes 600 x 400 x 200 go into a 20ft container?
If you cut off the end of that rectangle, you make it smaller, 2 * 3 and a separate nub of size 1 * 2

Any straight men had a gay experience in the past? What was it and how did you feel?
Move the nub up to the top:
n^2 - 1
(n - 1)(n + 1)
n^2 - n + n - 1
