lim |x-5|-|x+1|/x-2 x->2 so is this indeterminent? or can you solve this?? but im confused because of the absolute value, how can u possibly get rid of them?

I am taking calculus in college, but i was tought that when the answer is 0/0= indetermined, and that when a number/0 = undefined.....

Actually its the other way around. i.e. 5 / 0 = infinity =>infinity x 0 =5 this is indetermined

lim x^2 − 5x + 2. x->4 can anyone help me solve this please?

I think it's -2. If you try substituting x in the x^2-5x+2 with 4 or numbers close to 4, you get -2 or numbers close to -2. I THINK, but I'm not the best limits-person. Ask Sal ;)

This is amazing! You can teach so much better than my math teacher lol. If you could keep these up, that would be great! Just a side note, instead of writing out the word "undefined", just use the symbol. (the circle with the line through it) and just explain what it means in any future video/s. It should save you time :)
