@@adamc2846 i hope three years were quick enough. x divided by negative x is negative one, then 2 MINUS negative one -- two negatives equal a positive -- is 3. then in the denominator, 6x^2/-x^2 = x squared divided by negative x squared is negative 1, 6 divided by -1 is -6. so your answer would be 3/-6 or negative one half.
@@khosroyavari8914 can I like divide the numerator with the highest power in the numerator since it's different from the denominator because the denominator has square root?
@@johndysalomon6125first of all you look for the highest power of x in both numerator and denominator then you divide each term with highest power sometimes you can only divide numerator or denominator for the dake of simplicity
the seven would be divided by infinity, so it would get infinitely small and practically zero. That's why the 7/x^2 is just replaced with zero. I know i'm 3 years late, but oh well
First of all... You have a pretty significant mistake within the first 5 seconds of the video. I believe you meant the square root of x squared. Second of all, the long pause in the middle kills the flow of this video. Third... Another significant mistake. You're incompetent. I genuinely have to believe the positive comments attached to this video are fake.
I’m pretty sure that the square root of x does NOT equal x as stated at the start of the video. We all have brain farts, but if you produce videos they need to be high quality.
How is it that TH-cam gives better explanations than in-class sessions? This makes tons of better sense.
happy to be able to help!
this video saved me from wasting another hour in deciphering my assignment.❤❤❤❤🙌
cheers!
I am from Romania🇷🇴 , and I like very much, how you handle the math problems ... I want this style in Romania
Thank you for share
happy to be there for you, I have a lot of videos, hope they all can help
What if the limit was approaching negative infinity? Would the square root be negative as well?
i need the answer to that
no since it is squared on the inside
Yes...the value used for x will change depending on the limit is approaching
Thank you!
wow I've been blasting my brain trying to figure out a problem that can be solved this way.
you get straight to it, like it actually makes sense omg
Thank you very much 🥰
You are very welcome!!
Thank you for helping my assignment ❤️
you are very welcome!
Lynn Nguyen did it help you though????!! Hmmmm
wow you answered my question about how to know what +/- value to take from the square root at the end of my answer in 5 seconds lmao
This video are absolutely marvelous..easy to follow and comprehend
happy to be able to help!
Explained it the best 🐐
Thank you this helped a lot
You are very welcome!!
Thanks! Makes sense now..
awesome! happy to help Erin!
is the answer will change if the function will approaches to negative infinity??????? please answer my question as fast as you can!
Yes, you are going to be anticipating negative values. I hope 1 year was quick enough
@@aasavshah3183
Lol i hope u dont take a year to answer this
I’ve calculated it for negative infinity but it’s still the same answer

@@elizekine heeey thanks for your answer, even thought i dont need it anymore 😂😂😂😂😂 graduated from highschool already
@@adamc2846 yeah I know I’m totally kidding 😭
No need to Rationalize the Denominator sir?
If you were to rationalize the denominator, then you would then have a radical on the numerator, which then itself creates a problem.
you are hero !
how did you decide to divide everything by x^2
You divide every term by the highest power of the denominator

why is it 6/x^2 i was thinkinit was just 6since the X^2's cancel out
the square root does not distribute across addition
he fixes it later
Why x/x is 1 here? ,as x tends to infinity ,so infinity/infinity should be indeterminate,plz correct me if am wrong
Simplify first then take the limit.
Is the solution same if the radical is in the numerator?
try it by graphing in desmos
what happened to the number 7??
the seven would be divided by infinity, so it would get infinitely small and practically zero. That's why the 7/x^2 is just replaced with zero.
I know i'm 3 years late, but oh well
I like how the way he explain however..he always makes a lot of mistake....and he corrects them later on...really annoying...but good job though

The square root of x does NOT EQUAL plus or minus x!!!!
This guy is a liar. Infinity divided by Infinity will not always equal one.
Liar liar pants on fire, caught
Awful.
why?

While you do make a point, I think he was just trying to demonstrate the logic behind the concept of the square root of any number being plus or minus
