If you mean as what happens to it in factorization: (x+4)(x-4)= x^2 - 4x + 4x - 16 ; the fours get canceled by each other and you are left with x^2 - 16, as the example in the video shows. The way you can obtain this result is by thinking of a conjugate binomial Hope this helps and good luck :D
@@kaulincurtis9665 You didn't quite get me, I was proving that the limit of the function as x approaches -4 is well defined as -4 is a vertical asymptote of the rational. If x becomes infinitely close to -4 from the positives and negatives the function asymptotes towards positive infinity.
it should be 3/4 since the top and bottom are both negative. the answer should be a positive one
agreed
No..numerater= -3×-1=3..so the ans will be negative
What will happen if we factor out but still the answer is 0?
first example how did he get x-3
Which software are u using to teach?
what happens to 'x' in 2:27 ?

I dont get it. (-3)(-1)/-4 l, it should be 3/-4 right? Enlighten me
3/-4 = -3/4
Noo.. numerator is positive
even if the numerator is negative it is still -3/4 since if you divide -4 by 3 you still end up with a negative number
Sir thank you!
Please solve trigonometric function
The answer is 3/-4 please
I do not understand 😢these
great !
thankyou
DOES LIMIT EXIST IN THE FIRST EXAMPLE?
Yes, as x approaches -4 from the negatives and positives, the rational asympototes towards positive infinity.
@@dionysusheir4112 the limit for the first example is 7/8 as x approaches -4, not infinity.

Isn't 1 in the first example sir? The limit exists
It's surprising that time is spent "teaching" factoring during a Calculus-level topic.
A review is always helpful.
@@kaulincurtis9665 Not always.
I hate peple of coler
HELLO:
THE final answer is 3/-4
not -3/4
MUAADH ....its the same braaaahhh
it's the same thing.
😅😂
Hello? One of the times i wanna die
Yo. 3/-4 or -3/4 when these integers were in a fraction, then they do both give the same negative value how matter you look at it...
