@mathgcse Ya I'm doing higher (A level equivalent in scotland) I maybe should have looked at the name of your channel before commenting.

mathgcse commented on 17 Feb 2012

@CaptainZurg that will be for a level maths not really need it for gcse

explain how to do an 3x^3 equation. Everyone can do an x^2 one.

i have a ? on my HW that I am totally stumped on: 6y`2 - 13y - 5. I did your triple play method and it came out to: (6 y + 2) (6y - 15) ------------------------ 6 and neither side is divisible by 6! Please help me! I'm desperate and this is literally the only ? i couldn't get using this method!!! am I doing something wrong, or do I have to do something differently to solve with - signs?? THANKS

thanks for this, its really helping, but i dont seem to get it, its the problem, i have the right answers (she gave them to us) but i still dont get the correct answer and i'm doing everything correctly... any other methods that might exist? thanks again.

It's not really a hard trinomial because it has a common factor of 5. Take out the 5 and you have 5n^2 + 10n + 20 = 5(n^2 + 2n + 4). Since there are no two numbers that multiply to make 4 and add to make 2, you can go no further.

Thank you sir! I finnaly get how to do this now! I think I learn more watching your videos then I do actually in math class If you are, or have ever been a teacher, your students are very lucky Thanks again!

this is super smart my teachers in high school and in college did not teach us this way and it made life hard this is a nicer way of doing it.

Volcanoe00 commented on 21 May 2009

can you still use the same method for this quadratic: 4.9x^2 - 14 + 2 = 0 i dont know how to do it when there are decimals involved.

LifeIsHORRIBLE commented on 27 Apr 2008

OMG thank you!! You are a life saver!! I wasnt in class when she taught this and she wouldn't repeat her lesson to me!! THANK YOU!!

minkusbc commented on 27 Sep 2008

Yes, I do to, in that it uses strategies that are used over and over again in the course, whereas triple-play is a one-note wonder.

Leonard Dixon commented on 29 Sep 2010

That's an interesting bit of trickery! For teaching purposes,I prefer the "Trial & Check" method. Do you teach that method too?

Chitownboy1023 commented on 09 Oct 2007

You make it look so easy, it can be intimidating at first for someone who doesnt know how to work these.thanx for the help!

VBpictures commented on 16 Jan 2008

thank you so much for the save! i have a test tommorow on this stuff and im sure this is gunna help alot. thanks again!

okokokg commented on 08 May 2008

Thank you very much, my teacher somehow always manages to teach us methods to solve problems the hardest way possible.

Roger Weir commented on 14 May 2007

I remember doing these in school.....we had to guess everything.....what torture....Great videos...thanks.

IAMTEHSUGARGLIDERMAN commented on 16 Dec 2008

any advice is the C is a very large? like I have to figure out 300 for C and B is 37. thanks

minkusbc commented on 04 Oct 2010

@katylyssiesmom2 Yes, see my video on solving quadratic equations by factoring - minkusbc

GigofRAM commented on 02 Dec 2009

3x^3 is not for parabolas and would be factored using a difference of cubes i believe

playerboy1k commented on 01 Dec 2008

my teacher ms king is using it for a lesson she actually gave a packet based on this!

minkusbc commented on 18 May 2009

Must multiply to make 12 and subtract to make +1. Thus +4 and - 3 will work.

Rusty Stepp commented on 28 Sep 2009

this is cool... I wasn't even looking for it but this will help me out a lot

krazyliljoo commented on 24 Apr 2009

Yeah my techer explained that today, thank you for your response though :)

jgrande345 commented on 22 Nov 2011

Does this method work for (ax^2) or the (c) in the formula, or just (bx)?

nintendo1980 commented on 01 Feb 2010

OMFG why the fuck did my dick nose teacher never explain it like that!!!

motivation4u commented on 02 Apr 2007

Keep posting these short math lessons! They are very helpful! Thanks!

Mr. LargoFeet commented on 03 Nov 2011

Good god, burn the textbooks, ditch the classes and sub to this guy.

katylyssiesmom2 commented on 04 Oct 2010

Do you have a video for setting it to zero or using the zero method?

Michael Kal commented on 19 Oct 2009

I believe one would be 3x^2 and the other just being a 1x or 'x'.

TINBITZPHAM commented on 18 May 2009

How about 4x^2+x-3? what number will multiply to 12 and equals 1?
