Tell me why it took me 2 semesters to figure this out and now i clicked on this video and i FINALLY understand this in 8 mins………. Wow. I’m convinced Professors are gatekeeping. Thanks bro ✊🏻 you the goat fr

First, I factored the denominator to find the poles of this function. I got x = -1 and x = 4. Then, I factored the numerator to see if it shared any zeros with the denominator. I found that both the top and bottom were 0 at x = -1. So I did zero-pole cancellation, and plugged -1 into the cancelled function to see if it approached a finite value. I found that the function had a hole at (-1,0.4). So the function has a vertical asymptote at x = 4, and a hole at x = -1

Right, but this demonstrates *why,* not what. It's one thing to just say, "this is what it is, this is how to do it, just memorize the process". But by demonstrating the difference, how with one type the equation *would be* continuous if not for the discontinuity, but with the other it's an automatic V.A. in *in spite of* that one exclusion, you understand the reasoning behind the method.

The easier way to explain hole at x=a is if direct substitution creates 0/0 and the limit as x->a is finite. If the limit is infinite it becomes an asymptote regardless of the numerator being zero or not.

look at all of the boxes of markers he has in the background... literally straight out of a word problem haha :)

Thanks!! I was looking for solution when both sides of equation can't be zero. I know this one original is L'Hôpital way

Somehow I find L'Hôpital way more straightforward than factoring and reduction 😅

you first need to find what makes a number into that from multiplication so like, x^2-x+12 right? then what makes a 12 is 3x4, so it makes sense because if you minus 3-4, you get -1 but in this case, -x. I don't know if I got that correctly nor used the right equation, that's how I was taught
Why these two square root functions are NOT the same!
