Rational Root Theorem

How to use the Rational Root Theorem to narrow down the possible rational roots of a polynomial. You can then test these values using synthetic division to see if they are roots of the polynomial.

the fact that a 6 minute video that is half a decade old was more efficient and enjoyable then my teacher's 2 hour lecture is wild

[nesyboi]

My teacher was gone and assigned Edgenuity work while the sub was in, and the sub had no idea how to help and Edgenuity's videos overcomplicate things, so I came here and bam! Makes sense now.
You will not believe how many math videos overcomplicate things nowadays, thank you for being clear and simple, you really helped me and my classmates out a bunch!
thank you so much!

This was a very educational video. I like how you get specific about all the details and explain any knowledge needed before the next idea. Well done!

Ive looked at a lot of rational root theorm videos but this one is the best. Subscribed immediatly

[connorsucksatgames]

This is incredibly useful even 5 years later. Thanks Mario.

You are an incredible human being. Thank you so much for explaining this so easily. My son, who is 13 years old, is taking Algebra 2 in 8th grade. He is so smart but he is sometimes lazy and he does not like to do his research to learn. I have been helping him find videos which are not confusing and can get to the point.

[HanaManesh]

Thank you so much!
This is exactly what I was looking for and asked about in your new video's comments.👍

[wykes]

You explained it very well! Your videos are quite helpful.

was half asleep when my tutor was teaching, was half asleep when I watched this. Guess which one made the facts stick.

[syldris]

Totally forgot this that I learned it in Algebra 2, and now I came here to factor Characteristic Equations of Recurrence Relations for Discrete Structures course...
Thank you! It helped a lot!

[KrakenDoesEverything]

damn you're fast at solving, you deserve more subscribers sir

[aliceemerson]

You're an angel and a very good teacher, I appreciate you so much. I hope you're doing well.

[shargor]

This is one of my most favorite videos on Youtube. No BS.

[eliteturtle]

Im kinda relying on you to have the right video now that im on zoom and not paying attention in class, so thanks, and keep making more vids plz.

[tweetiebirdgaming]

Your better than my Teacher in Algebra😂co'z i can't understand when he's teaching to us

[stevewest]

Thanks Mario!
Just one tip to add... You can factor out 2 from the original function and that will reduce the possible number of roots and get rid of the fractions :) .

[angelikcakes]

thank you so muchhhh i love the explaination you gave rather than me just blindly following steps

[elostroymauricnerbieran]

The moment you gave me how to find P and q, I instantly know what the hell I should do. Our book was so untouched towards their audience, like come on man, show and tell! Not tell and tell, give us some arrows.
I don't want to sound like a boomer but back in the day, they at least have some kind of clear directions.

[jeshwanthpalakonda]

wow, this was way easier to understand than the lesson I read!!! Thanks so much😃

[jayden]

I love how you teach to the point. thank you
