Limit with Conjugate

We can just use Hopital's rule to find out the answer in 3 seconds. The derivative of the numerator of the fraction divided by the derivative of the denominator of the fraction

1/0 you can't use it yet

ngl I would have used hospital rule (I know that isn't the name but it's easier to remember like that). I'm glad to see there are easier ways to solve it, I should try looking for easier ways before doing it the long way.

A question, why do you always have to explain that (a+b)(a-b) is indeed equal to a²-b²? And if tou have to explain for the sake of explanation (reasonable tbh for theae styles of video, hands down), why do you always use the actual numbers instead of just explaining it in abstract? Saves time and more importantly saves mental power of the viewer.
