I must say you have definitely provided clarity for me with your detailed and informative instruction. Much appreciated!

Thanks for the comment, Tanya! I'm so glad that you enjoyed the lesson. I hope that you can give the video a thumbs up, subscribe to our channel, and continue learning math with us! -Anthony :)

I really thought I had finally found a video that would help me get this. The first part was great and then suddenly you just said the answers to the the quadratic equation while solving for X with no explanation of how you got there. Isn't that the point of a how to video? Anyway, it looks like a lot of other people magically got it so who knows.

[@RavinderSingh-ie7ii]

I was struggling in math but this video helped me so much, thank you and you explain the thing so good 😊😊

[@jeffersonjarrell33]

I'm lost at 6:48 I don't get how he got (x+3)(x+2). Where did he get those numbers from?

[@stephenposton948]

Yeah I needed a little context he skipped alot.

[@angusmcalister593]

It's a quadratic trinomial.
x^2 + 5x + 6
P (product/last number) = 6
S (sum/middle number) = 5
F (factor/two numbers that add to give 5 and multiply to give 6) = 3, 2
(x + 3)(x + 2)

[@amandasteven1400]

jefferson, math skills are directly proportional to how much TV we watch... and indirectly proportional to how many video-games we play :)

[@saihajmangat2995]

He factored it. You should search for a "factoring quadratic equations" video.

[@Matevoz72]

whos watching this for school

[@butler-diazfamily1335]

not me

[@duprewillams2819]

No body is watching this for fun

[@synergy1916]

Everyone does

[@LostinTranslation479]

I'm watching it for the entertainment duh

Thank you dude thank so so so much ❤❤

[@MUHAMMADNAIMMOHAMEDKHAYN]

Thank you sir

[@jorumssenkubuge-dn1jj]

What a nice explanation thanks am Lilian

[@ktf8]

thanks you, but if someone doesn't know factor yet, this could led them searching for another factor video lmao, but thanks for your valuable information!

[@MrDhanesh2nair]

Thanks a lot. Your videos are very very informative and gives an idea of how algebraic equations works.

[@MashupMath]

+Dhanesh Nair Thanks, Dhanesh! I'm so glad that you enjoyed the lesson and hope that you can subscribe to our channel! -Anthony :)

[@hanabiilesley]

thanks, this helped me

[@Ks-oj6tc]

Well explained.

[@saskos3800]

thank you. this really helped

[@saskos3800]

thaaaaaank yoou. this really helped

[@boothd858]

Thanks so much u helped me solved my problems on webassign for college 😊🙏

[@braadwellcastro3287]

Thank you!!!!!!!

How would u find the y intercepts for this
0= 24x^2 - x^2 + 59 -357

[@saihajmangat2995]

Assuming that you meant y=24x^2 - x^2 + 59 -357, not 0= 24x^2 - x^2 + 59 -357, because that would be an equation and y wouldn't exist, here's how you would do it.
Step 1: Simplify.
24x^2-x^2= 23x^2
59-357= -298
y= 23x^2-298
Step 2: Substitute.
y= 23(0)^2-298
y=-298
OR (on TI-84)
Step 1: Enter "24x^2 - x^2 + 59 -357" into y=
Step 2: Graph with appropriate windows (you may have to change them a few times)
Step 3: 2nd, trace, "minimum"
y= -298
If you watched the video then you would have been able to solve this yourself. It was a question that reminded me of middle school so thx for the nostalgia.

[@saskos3800]

thaaaaaank yoou. thos really help

[@topeka321]

this is good but please for the love of good those sound effects are cancer

[@kareemabdelwahab6948]

ong bro

[@jasonroberts9788]

But how did you factor ? You were doing so amazingly explaining this until you just did that part in your mind instead of in the video!!

[@amandasteven1400]

Jason... factoring is covered in previous tutorials. this tutorial deals with evaluating quadratic functions for the x and y intercepts. which is why it's titled... "HOW TO FIND X and Y INTERCEPTS :)

[@lmong]

sounds a little like daily dose of internet. good video though I have a test in like 5 hours

[@alliahayentanedo627]

nice😂😂😍😍
