i just had to like it xD

[wynduu2]

Thanks for uploading, this is so helpful.

[patrickJMT]

@wynduu2 no problem, lots of other videos, so come back any time

[elmegapitondelnorte]

Thank you so much this helped so much!

[jamesfraza]

thanks :)

[Johnlmeck]

thank you sooooooooo much

[RespectMyHate]

I mean I like khan academy but your math videos are just better.

[patrickJMT]

@RespectMyHate thanks :)

[ArtsySoul07]

@RespectMyHate I completely agree! Patrick is quick, and to the point. To be honest, I sometimes don't even understand concepts as well with Khan Academy.

[blindsniper105]

Your videos are really good, much appreciated

Thanks man! I've been following your videos for a month now and I bumped my math grade from a 77% to a 96% (Honors)! :D :D :D

[patrickJMT]

@PATRICKxSTRAWN sweet, congratulations!

[Tibiaal100putos]

4:42 looks like it is a 13 but, ty man i finish my homework. I wish that's the right video because my teacher teachs me in a box thing xD

[LifeizzBeautiful]

[Gaurav1823]

You are the best! I CAN'T TELL HOW MUCH THIS HELPED ME! I love you!!

[IdiosoAmericano]

Dude why is JennaMarbles on the suggested videos. It is distracting and very interesting to find it related to Difference of cubes.

[patrickJMT]

@IdiosoAmericano me and jenna are good friends. we include tags in each others vids

[abcninja5]

be my teacher

[MrGrande8844]

I would rather my tax dollars go to you teaching rather then the fucktards in the system right now. I LOVE YOU.

[3im3arLuvsSheep]

Thanks! I've been out sick for 3 weeks and hadn't a clueeee what was going on with this. Really helped:)

[lizziebieberforever1]

Thank You!!!!!

[H2kPrograming]

Thanks man! really helped

[anguelmetodiev]

Thanks man

[sonnytenedo]

Why do I have to be bad in math... but good in science and language :(

[UruguayoMatias]

@sonnytenedo It's all in your head, just work hard at math and pay more attention, and you'll do better, i used to suck at math and now im in an honors advanced class.... i just study and work hard at it by focusing on it. Good luck, hope you get better!

[yaimrandome]

AHHH It just clicked!! :D

[patrickJMT]

@yaimrandome perfect!! : )

[reneeniecy]

thank you so much:)

[lipteased]

You. Are. A. Math. God! Thank you so much, I'm completely dumb when it comes to math yet you put this in such a direct and easy way and I now understand this. Liking and subscribing :)

[MagnisiumOxide]

My man! You did it again!!! Getting an 86 in adv functions because of you! :D

[patrickJMT]

@MagnisiumOxide that is very good! study just a bit more and get it up to a 90%!! : ) you can do it!

[heartbreakofthelost]

Are you a teacher or do you just do lessons on certain subjects? These are great helpful videos

[patrickJMT]

@heartbreakofthelost i used to stand at the front of a classroom and bore people. no longer though.

[Hardy123Zhao]

Don't you have to factor the trinomial at the end too?

[Beastking50]

DUUUUUUDE!!!!! THANK YOU! I'm in math 103 and damnit I HATE THE SPECIAL PRODUCTS FOR CUBES!!! Difference of squares is dope but I hate cubes! You do much of this stuff?

[Selena95918]

Thank you, sir. When you fall asleep in class, make use with what you got! :)

Three cheers for technology!

[SagaraSouske]

Thanks for the help. Awesome instructions.

[Rhysabdeen]

Wow your videos are so helpful. I really want you to know this because I dont know if you read all your comments but I am so far ahead in my math class and everybody is surprised by me this year. Most of it is because so far in my polynomial unit you have a video for every lesson my teacher gives. Its like a having a free tutur who comes whenever i want and teaches me in the most direct way for free. Believe me im pretty broke right now but when I save up enough imma make at least a 20$ donation

[patrickJMT]

@Rhysabdeen happy that i can help you out : ) spread the word about the videos!!

[whatstheverdict]

how would you do something like (p+q)^3-(p-q)^3

[Matterboy81]

wow thanks.

[RyBoSG63]

thx so much. this helped me alot.

[Thiessu]

lol math is easy

[Seanopp7]

never knew this formula until today..thanks!!!

[darth2499]

how do you do 2y^3-16?

[TheSorceressKnight]

@darth2499

2(y^3-8)

2(y-2)(y^2+2y+4)

[xBazingaProductionsx]

Thank You Veryyyyy Much!!! :D

[jocsoncedrick]

ty man nice vids

[suavion]

thank you.



[eldogg4life]

FUCK!!!! Got a test tomorrow!!! Thanks

[AChemicalRomance27]

thakyou very much!!!!!

[jkoscak]

THANKS

[chico280]

Keeping the formulas handy and using them sure beats staring at it for a half hour and pulling your hair out. Thanks!

[ogsophie]

thank you so much!

[theslayer1994]

You are left handed :D

[anababy28]

omg! i was breaking my head!!

but wow!!... you actually did my homework!!

thank you!! :))

[clouduzumaki1]

Since when did math tutorial has 1 disllike??? i think he or she failed

[lesoiree]

You are a legend

[karamathus]

I think the answer of this sum of cubes is : (3y - 2)(9y^2 - 6y + 4)

because according to the formula you are multiplying 3y by -2

but thanks it is really helpful.



[collinhendrix]

AAaaaaaaaaaamggpmfffggfpfpfpmf­m "

[TheFilipinoCreww]

How do you solve x^3-125=0.

The result I got was (x-5)(x^2=5x=25.

The question on my HW is to solve it by factoring, & the given answer is x=5.

What do I do next?

[callmecrazynails]

LIFE SAVER!! THANK YOU!

[changeisnowpeople]

ohhhh woooowww......... great!...... thanks a lot.. i m in 12th... i m having troble in limits and this helped me alot.. thanks..........thankzzzzzz...­..... can i get all set of the factorising formulas.. and more sums to practise on factorising.... :-)

[WitnessTheTestament]

I see your left-handed. Thanks for the help

[jdp2496]

A little rhyme my math teacher taught us to remember this. "First write it without the cube, then, square the first term, product of the two, opposite sign, add the square" Lame but useful :D

[barrycuda68]

Great videos, wish my instructors were half as helpful, if you have time, could you factor this out (h+2t)^3-h^3 thanks

[18browneyedgirl81]

thank youu, this really helped!

[sandmansamperson]

if Chuck Norris was a math teacher this would be him

[nm2941]

how do you factor 8x ^3 - 64y^6

[patrickJMT]

@nm2941 you can rewrite 8x^3 as (2x)^3 and 64y^6 as (4y^2)^3 so that you have: (2x)^3 - (4y^2)^3  and then you just use the formula.

[MysTeri0usMatT7]

@patrickJMT excuse me sir, but could you help me with a backwards problem like this one: 8 - z3 ? the reversing has got me stuck.

[ObamaSucks12345]

@MysTeri0usMatT7 hahahaha your such a dumbass. 3z and z3 are exactly the same fool

[MysTeri0usMatT7]

@ObamaSucks12345 okkayy...I'm a dumbass?? first off i wasn't debating on whether z3 or 3z were the same, I was wondering how to work the problem in reverse rather than 8 - z3, i wondered if you could rewrite the problem to z3 - 8. I already figured this out, but that's all i was asking.

[patrickJMT]

@MysTeri0usMatT7 dude, do not let this guy bother you. he seems just like a trollin' douche bag. i had to block him for being such a noob.

[MysTeri0usMatT7]

@patrickJMT lol nice, i just hate it when i try to ask something and i get a hateful meaningless reply back from some random a-hole. Hey great videos you have by the way, watching your vids while working really boosted my algebra 2 skills. I'm homeschooled(12th/teach myself) so its cool being able to work and have some help from here:) thanks man

[patrickJMT]

@MysTeri0usMatT7 glad you like the videos and: welcome to the internets, the planet of the apes.

[MysTeri0usMatT7]

@patrickJMT loooll thanks mate

[nm2941]

@patrickJMT thx MAN! ur a gift form above!!

[ttlyluvsasuke247]

you are my savior, I was dead lost in my class because my teacher rushes through this stuff and now I understand. Thank you again my good man.

:D

[patrickJMT]

@ttlyluvsasuke247 if only real life had 'rewind'

[Killuminatismd]

This guy is incredible. Hes got a super extending brain, that extends from negative infinity, to positive infinity, and has a derivitive of the 3rd radian and 5th bisector of the 0.5 transformed semi-factorial and can handle dual inequalities and his right eye looks like the factor biotheorom! aka your awesome

[patrickJMT]

@Killuminatismd loool

[Phunnyazngai]

you are an amazing teacher. Thank you so much for this.

[XxTreceZxX]

OHH YEAHH.....tnx for this.....wish I could perfect our exam x3

[XxTreceZxX]

what if the problem has 2 perfect cubes like 125x³ + 8y³ and the answer was

(5x + 2y)(25x²+10xy+4y²) very different from what u said.....

[CamiloSanchez1979]

sweet..

[lordthorpez]

YAH!

[DETROITSSAVIOR]

VERY HELPFUL YOU ARE SMART THANK YOU VERRY VERRY MUCH...WISH ME LUCK ON MY TEST TOMORRO:*

[patrickJMT]
