Pre-Calculus - Solving rational inequalities

[@awabyutoo4668]

The way he writes is so satisfying and comforting, also he's so detailed that I understand it easily

[@MySecretMathTutor]

Thanks! :^D

[@thekookiegirl853]

Great job brother. I was drolling over it for about 2 years and no teacher was able to describe the actual theory. I'm indebted to you for whole of my life

[@aiseiku5539]

I hope this guy is my teacher. Online class sucks. The teacher doesnt even explain the lessons. They just keep giving us piles of work without a proper explanation. Instead of teaching us step by step during the session, they upload examples with unclear steps of solution.

True that brother

fuck online school all my homies hate online school

the one you mention the "uncleart steps" its real for me, Like where did that number come from

[@anontob]

Ong bro, my class' teacher is so useless. She can't even solve questions by herself without my classes own help.

[@ivbtw4433]

@@anontob bro same she would literally let my classmates do every example and then does not explain it. Like fam what the fucj

[@charliestewart885]

i literally love you. there’s not a single other video on youtube on harder quadratic inequalities with fractions.

[@fair.yspirit8889]

my pre-calculus teacher doesn’t use a table and tells us to change signs but it’s so confusing! she doesn’t want us to do it any other way so thank you for giving a better explanation than her. i’m not doing too well in class but watching your videos is giving me hope that i will pass!

[@robertcampomizzi7988]

One time I came home and was struggling with a formula for physics. I asked my dad, who was an engineer, what the hell was going on. He looked at it and asked, "What are toubteying to solve for"(the final temp of mixing two liquids). He said use this formula instead. I showed the teacher.. he double-checked that it was a better rearrangement of the same logic, and the teacher quickly announced, "ok, Rob is gonna be teaching the class today... so I did. Here I am 25 years later trying g to catch up again

[@TheNixChan]

I know this is an old video, but you're seriously my savior, thank you so much secret math man

[@mauricecolon4359]

I like this guy clear and precise !!! great job makes my life easier we need more math teachers who speak clear English .. its torture in these colleges with the math professors

[@Tony_Trixter]

i know right

[@Tony_Trixter]

my math teacher was explaining why you could randomly pick 2 points from a line in a line graph to calculate the gradient, and she was speaking for 20 mins and i still didnt understand and then when my friend taught me he literally said the most simplified thing in the world..... he said from across the class, "It's because it will always give you the same answer". My teacher was so happy and she was like, "Yes, FiNALLY", And i was in my mind thinking, " The fuck woman...you could have just said that 30 fucking minutes ago when you were fucking replying to my friends on why they could randomly pick 2 points..." DO YOU KNOW ENGLISH?!?! SIMPLIFY IT!!

[@bienangelo9161]

@@Tony_Trixter FACTS, THEYRE TEACHING STUDENTS NOT LIVING MATH DICTIONARIES

[@Tony_Trixter]

@@bienangelo9161 uhm... If they cant understand how to speak clear english.. Then just dont teach math... She made her undefinitive 30 times longer than it needed to be. When the answer was just 4 words. *"ITS ALWAYS THE SAME"*

[@paigefitzmorris649]

This is the first vid I could find with a rational inequality of this type where you needed to make the constant numerator into one with the variable in it. FINALLY

[@Arion661]

Oh, man. You saved my life for the pre calc test I had. Thanks so much!!!

Oh my god thank you!!!!! I am Korean students who is studying pre-calc in USA, and this made me understand things way more better!!! THANK YOU SO MUCH!!!!

You're an amazing teacher. You make things so simple and I am glad I found this video since I've been sick and out of school missing this lesson. Thank you so much!

You don't know how useful was this for me. Thanks

[@robertcampomizzi7988]

This is the EXACT thing I wanted to learn today! Except I didn't know the term "rational inequality " as such.

[@hassan3kb]

Thankyou so much!!! I wonder after visiting more than 10 websites i understood this concept here. May God bless you.

[@bowsi9]

Best tutorial on inequalities in youtube, I would appreciate if you included the number line for visual learners like myself.

[@MySecretMathTutor]

Great suggestion! :^D

[@joannis-f9h]

Thank you, for your awesome calm soothing voice tutoring. Understood in minutes what I could not understand after weeks of class..

[@odgarig8601]

Wow It's SO much easier when you write it down in a number line like that. I was trying to do all of it in my head.

Thank you sir for the clarity by which you make solutions to rational functions look easy.

[@ramlahassan9761]

thank you so much. this made it sound much easier. coherent explanation and we sure need more teachers like you!!

thanks a million bro you saved me from the teacher

[@whitemango9928]

Hi, first of all i would like to thank you for this video, it IS really helpful for those who are struggling with how to use the table method to solve rational inequalities. I used your type of solving method for the table method to solve for my homework. My lecturer said there was inconsistency in my work.. the thing is... how? i had a really long talk with him and i was really upset afterwards. The thing is, he said to follow the majority and i was surprised because math is a universal language which can be solved in MANY different ways. And now my grade is at stake..again, thank you.

[@MySecretMathTutor]

Unfortunately there are some instructors who take the view that there is only one way to perform certain task. Even simple operations like multiplication can be done in a variety of ways. Keep working hard, and don't be afraid to seek out other ways. When your grade is at stake, sometimes you just have to go with the flow, but never stop searching for others ways as well. :^D

[@Shadowsoldier413]

[@Stephanie-rg5ln]

Yes!!!! I have an assessment tomorrow and this totally helped!!

This is such a good video. Great explanation. Thanks

[@edwinpious5381]

This really was a hard topic, now I think I can ace these type of questions....

[@Miss_you_meow]

Wait shouldn’t the x value be 7/9 instead of 9/7??

[@Miss_you_meow]

9x-7 will have a 0 of 7/9 so I’m confused to why he wrote 9/7

[@MySecretMathTutor]

If I'm looking at the same problem it has a -9 + 7x. Note that the x is on the 7. This will give us a zero at 9/7.

[@HaHa-ts6ei]

Hello teacher, how the denominator can be equal to zero 4:38

[@sanya5538]

wait I'm confused. Doesn't square brackets mean less than or equal to or the opposite way and that not square brackets mean not less than or equal to? I don't get how you solved the last problem.

why not to use multipication inverse like multiply both sides by 2-x/4 then continue solving ..... plz answer me

Excellent tutorial

[@mushroom69690]

How would I write the answer in terms of, inequality sign? ie, x>0 ..ext Thank you! great vid

[@encikazhar9573]

For the 1st question, can we simply bring (1-x) to the right? Become (-2) < 7(1-x)

Thank you so much! This was really helpful ☺️!

[@bananabread4082]

I have a question, It is always negative when you transpose it?

[@MySecretMathTutor]

I'm not entirely sure what you mean. Do you mean flipping the sign if you divide or multiply by a negative? This is one of the rules we have to follow when working with inequalities.

[@jesse_tc7]

Thanks teacher ❤

[@kpoppin6167]

Tks bro. Great job......

[@DJizz82]

When solving this rational equation can I combine like terms, and set to "0" after this step (mid way through the problem): 5x-10 ≥ 4x-12 x+2 ≥ 0 x ≥ -2 Also, can I use x-3 ≥ 0 and x-2 ≥ 0 in order to test my additional points ? x ≥ 3 , x ≥ 2 sorry If I made this more complicated.

***** why not?

[@benpritchard2716]

At 11.10 how come you couldn't cancel out the (x-2) and (x-3) ? Thanks

[@yosef6325]

Hi, an answer 5 years later, because why not, haha. You don’t want to cancel anything in the denominator as it’s used to find the intervals (ex, in this case x=3, x=2 isn’t defined).
