he posted this vid on 2008.. but still the kids of 2014 are still learning from it.. thank you man for doing this and saving humanity LOL.
i just cant believe how far a simple but good educational video can do, he did this without asking for anything in return..
thank you so much sir
you're one of my favorite math youtube teachers
It's 2k17 and I'm here, reviewing with this video... :D
Thanx
* 2018
continues in 18 too
still here
a 15 year video teaches me better than my teacher. Thanks!!
Thank you man thank you......10 years have passed since this video was uploaded and still in 2018 it helped me out soooo much ... Thanks for your efforts ...
@patrickJMT, this video is excellent for a few reasons. The set up in the beginning is extremely well done, you showed examples of different types of rational inequalities, and you described the general process of how we go about solving them before you even started your example. It felt like we were all on the same page before we got into the meat of the problem. Thank you so much.
I like died understanding this lesson when our teacher diacussed it but when I watched this video, I was like... "Oh... So that was how it was done..." Thank you so much! 😭
oh my god same!
It's Oct 2020 and I find this video pretty helpful especially during this whole pandemic making it hard to learn math online!
glad it helped! my hand writing is normally that of a first grader, but i try to keep it clear in the videos!
He teaches better than my math teacher...
+winderson guimaraes Lol I bet you that is why we are all here! My math teacher sucks!
winderson guimaraes same
Same dude
@dirt0jumping
couldn't agree more
you are an awesome teacher...learned more in 10mins than an hr of class
@AWPNubDiesel come back whenever, i am always here!
For the last rational inequalities' solution set - (-1,0) U [1, infinity)
well you 're simply the best math teacher
@nLoL2 i used to stand in front of a board and bore people, yes. not any more though.
maker of this video is one of the greatest human beings
thanks
Thanks Mr.Pat!
now i can kick my math teacher ass , i love you
I was sick so I didn't go to school. My friend told that we learned radional inequalities. My first thought was Patrick would have a video on that...and you do. Thanks! :)
thank u
ur explanation is really great
You are a good tutor man
thank you sir..you really helped
@nouh220200 to determine which intervals of numbers work and which do not.
Patrick is the best math tutor on youtube!
youtube had a 10 minute limit before?
valarmorghulis sad days, also please rate this video 5 stars
A great quick explanation, thanks!!!
Brilliantly stated! Excellent way of breaking down concepts into simple to understand terms.
@patrickJMT what kind of books??? just wondering
WoW, you are the best teacher I have ever had. Thank you, Thank you, Thank you, Thank you, Thank you ;)
Its 2020 and he posted this vid in 2008 and still we are learning from this❤
I'm not in high school yet, but this video helped me understand this concept a little more, thank you!
yep
Your so much better than my precalculus teacher
Thank you so much, I needed that help so much; don't know how much this means to me..Thank you.
Thankyou soo much Patrick... Great videos...:D :D :D helpin mee soo much..:) Thx :)
I watched this at 2017. Thanks!
@mundorff92 no problem!
Simple and straight to the point with a touch of clarity. Ever considered teaching as a profession?
Thank you so much!
This helped a lot!
You are the best!
Hello, do you have a video with solving rational quadratic inequalities? Or is it the same strategy as in this video? Because Quadratic Rational inequalities will come on my test! Answers is much appreciated, thank you :)
How did you know to test 5 for the intervals? Is it just any number?
Thank you so much!! My teacher was tryin to teach this and man were we lost. Your video was clear, detailed, and straight forward. Thanks again. By the way did I mention you have reali neat writing?
i've been watching you for a year now!!thank you so much for everything!!
my tears of frustration just dried up!
Thanks a lot!! U r a great teacher!!
@wolski888 What part of Canada are you from? I'm from Manitoba and we use Union. So, not just a U.S thing.
woow really words cant define my haapiness thanku
THANK YOU SO MUCH THIS SAVED ME
On that last problem, would you end up multiplying that x in the bottom denominator out? You have x(x+1); would x^2 +x be more difficult or not matter at all? I'm just wondering if there's a reason you didn't.
Which is better, this method or a sign table? Thanks for the video as well.
is (-infinity, -2) correct interval notation?
@patrickJMT so what do you do now?
Hello sir, i have done lots of problems using both method of finding the associated equation then solving using this method then intervals where i have understand the intervals whether open or close but since using that method to bring fractions towards one side and then finding P(x)=0 and Q(x)=0 (those points) so here i didn't understand whether intervals would be open or close . Thanks : Regards Ahmed
I went from tears of pain to tears of happiness.
@goofguy316 thanks. glad i was able to make some sense out of it for you
well, you can always post questions on videos or through my youtube account. be warned though that i get about 100+ questions a day and after working 12 hour days myself, i usually do not get around to answering many of them!
You are the best math teacher on the internet! Your handwriting is clear and legible as well, keep it up! Definately Subscribed!
@lavendretta you do the same thing
Thank you teacher its relly help 1/5/2019
thank you!
Thank you
glad i could help!
@roxxyroll3r i hope the test went well!
That helped thanks !!!!
i dont understand the or, and inequalities problem from school, would show us how to do please
You are saving my grade. I have an A because of your tutorials.
you are awesome!
@karim7ahsan glad i do not have to grade everything : )
@AflakAttack good luck on the final!
July 21, 2019 thanks this help a lot
Your a legend
can anyone tell me why you cant simplify the last fraction to just -1/x ?
-1(x+1)/x(x+1) should equal -1/x right? (eliminate (x+1) on numerator & denominator)?
Is union or "u" used in the US? because I'm from Canada and we use just "OR"
Now i can make my report thank you
@spikeeleslie minus sign is meant to be a less than sign
Wait.... but for the last problem, why is it bad for the top part to equal to zero? Wouldnt that still make it true, since zero is equal to zero, and the sign says greater than or EQUAL to?
thank you sir! ☺
dude u make more sence then my math teacher...
my pleasure! glad to help! this is the same stuff i show people that i tutor, only i charge a lot of money to show it! : ) of course, the only problem is that you can not get any answers from a video when you ask them!
good luck!
God bless you man!
For the last one I got X E (-1, 0) U [1, infinity). Who else got the same answer?
yeah you right, dude
That's what I found.
I got that -1 ,0 ,1 are not equal to or less than zero but infinity is .
I have 2 questions
1)if -1,0,1 does not satisfy the equation then why do we just write them in solution set ,and if we write them then why 1 is opened with this bracket ? ' ] '
can u show a graphical method?
I have one question: I was always taught when you had an equation that has a "Greater or Equal to" sign you shaded in the dot, but on your second example you left it open meaning "Stricter Than", you explain it as being "undefined" how did you figure that out? Thanks so much in advance!
I have a question. Is it possible to get one "open circle" and one "closed circle", caz thats what i got
Is this the algebraic way? or graphic since you use a number line..which is the x-axis.
the most flattering comment ever!
however, once you mentioned babies, you lost me. typical guy, i guess.
still, very nice of you. : ) a lovingly cooked meal is always most appreciated.
These are great videos. Thanks for taking the time to make them.
@mbsimmer stand on the corner and ask for change. sometimes i go to the public library to freshen up and make a video while i am there.
no problem!
I am in the 11th grade watching this. Lol keep up on your math kid, it really will catch up to you.
How can you do this without a number line? By changing the sign or something like that, that's what I'm stuck on. My book calls it, "Considering the variable."
Thanks
aww yea! : )
@rockangel7777 i have been here for about the past 2-3 years, i do not know about the rest of it!
Could you do 2/x>(or equal to) x^3.2
Wouldn't the 2nd problems answer be [ 3, ∞) ? Because the original inequality asks for ≤ 0 not just < 0 ?
+John Baumhauer You can't include 3 since it makes the denominator 0.
Man you know my math teacher makes these rational inequalities all complicated. with many exponents, and canceling alot if they don't matter on making the equation positive or negative
thanks! : )
You are amazing!! Thank you sooo much! I can actually pass my test on Monday lol, thanks to you. You were much more helpful than my teachers lol :)
where are you located? can you be my tutor?
@faizcube007 but 3 didnt satisfy the inequality becuase it was undefined
