Pre-Calculus - Solve a polynomial inequality using a table

[ewaasay]

Damn I really spent an hour crying over my textbook example but you sir, are a blessing

[jazmineforoughi]

thank you so much my teacher can't explain anything

[ZicoTops]

Wow is this how simple it is? Thanks so much!

[Melissa-lpqe]

Honestly i love math and i felt dumb when i didn't get this and my teacher was doing a horrible job explaining this helped so much!!! I also never comment on things... but this was just so helpful thanks a lot !

This is really a relief. I have been struggling with signs and their tables but this explanation made things

[craigroxburgh]

You have saved me for my mid-term exams. Never been properly taught these so thank you so much!

[cchristiann]

this man singlehandedly saved so many confused hons alg 2/pre-calc students from a bad grade on a test

[Redemptionn]

Thank you. This really helped. The moderate pacing, repeated examples and clear explanations are a nice quality of your videos.

As an adult student, havingto take a College Algebra Plus class online, with an ALEKS component. I so appreciate you explaining this. You gained a subscriber. Thanks so much.

Thank you so much! This was so helpful for my exam next week. My silly teacher didn't know how to explain this properly, thank god i came across your video 😅

[lizzyinthahizzy]

That was perfect, thank you for including a more complex problem towards the end!!

[gencurie]

thank you SO SO much from Kazakhstan! we’ve started calculus 2 this year and I saw that I have a problem with simple things such as chart sign, and noticed that my teachers just said basic stuff like “look at the sign of first x and change them as you go”. it could work for simple ones, but I like this method more :)
thank you so much, hope you’re having a good day! you’re wonderful teacher

[HA-ykbo]

it's a miracle that I found your video few hours before my exam, thank you!

[dixiesutherland]

This was so helpful and clear. Thank you so much!

[jimmykayson]

This guy deserve a like & subscribe. (I have a math test tomorrow and I don't have any ideas what my lecturer was talking about for 3 hours)

[Explorer]

good job. the text books are generally horrendous at trying to explain this!

[jacobc]

Never seen someone so precise with a dry erase marker.

[qiuhongyu]

It's so easy to understand watching your video. UGH <3 <3

[RaniRani-zttr]

Omg thank you I have an exam tomorrow and it is 12:30AM here. Such a life saver

This was the most helpful video ever. With quarantine in place, my teacher gives me video notes (taken herself) and talks through them, but sometimes will not use the notes at all, and if they're poorly explained the book cant help you. Seems like the sign chart was one of those days for her, shes got us testing today and I think I'll do better than if I hadnt watched it. I was wondering why all the factoring was so important with her notes, but I get it now!!!
