Can someone actually solve this determinant?

Can someone actually solve this determinant?
Thanks

Not doing your homework.

Yeah, but it doesn't take a genius to realize this is just something your professor gave you to see if you understand determinant properties, so you can do your own homework.

wats a determinant lol

Use induction or something

yeah I know but I'm sitting here for 2 hours doing everything and still cant figure this out

Damn really? I am going to help you out of pity. You did not ask to be born retarded.

Dude, it is really obvious. Here is a hint: Add up all the other columns to the first column and see what remains.

The determinant reduces to two smaller n-1 determinants, which reduces to two more smaller determinants etc...

>Being this low IQ
Do what is instructed in and then it reduces to just one smaller determinant.

I've never worked with determinants that are bigger than 3x3 before and I really need to see how the fuck i work with these.
