got a score 44/50 on my quiz because of this! Thanks Sal!

[@diegoalejandrosarmientomun303]

i would be mad i should get at least 50/50

@@diegoalejandrosarmientomun303”at least”? that’s the highest score you can get … 44/50 is good lol

[@levii930]

"This something" and "that something" helped me so much lolz

[@FernandoFloresLopez]

Oh my gosh thank you! My algebra 1 teacher talks too fast, and this method is even more easy than she taught me!

[@twiceizone7233]

Easier

[@fredlee9362]

Fernando r u in grade 9? Bc we learn this in gr 9 where I live but I’m confused why some are learning at gr 6 or 7

[@fredlee9362]

T u r t l e m a n what do u mean by basics

[@fredlee9362]

Oh forget it

[@sharp4ce378]

What else method is there...

[@PimpMatt0]

Thanks for refreshing my mind. I came to class late and had no idea what the teacher was lecturing about. She talks pretty fast. Simple stuff.

[@theonetheonlychickenpermis3321]

thanks. I needed to refresh my skills. also do you notice there's so many views but so few comments?

[@sk___4206]

We are all in a hurry

[@idontknowok5632]

Lol same my Math exam is tomorrow

[@molten_bread]

I was totally overthinking how to do this. Still a life saver over a decade later

[@sarahpaulson5620]

Wow, So you just combine like terms! 😐

[@theperson4yearsago565]

LOL!

[@ethanbolen2172]

Thank you so much! I have been struggling in school because I couldn't understand what I had to do but after I had watched this video it all made sense!

[@saudalkaabi3353]

Now I know why my math teachers have been like “ if you don’t understand, do the Khan academy assignment “ jeez, I was freaking out cuz I’ve got a test today and I forgot how to add polynomials, Sal fixed that in 2 minutes.

[@ploppy421]

Thank you!! This really helped me a lot because I was absent from school the day we learned this.

[@mikafigueroa8781]

Thank you so much, Its really help in my assignment!

[@andrew-lh6lc]

there's an error its 14x not 15x 1:28

[@claudettemooney954]

notice how he fixed his error tho

[@justyourcoolgrandpa1384]

tnx khan academy u helped me so much in my homeworks

[@italianstallion929]

I got a 99 on my Math Exam bc of this!! Thanks!

[@rangerocket9453]

You can also do this in stacked format by combining like terms in parentheses

[@mijumaru14]

thanks, it really helps my final exam! and it is easy to understand

[@mumtaazburhaan3743]

shut up

[@mhyaruffy3341]

Thanks so much! I get it now

[@MulrxiYT]

omg it really helps me! and oh gosh my heart is pumping hard, the our exam will be like forever!

[@Sei783]

I had a student who asked if I could help him. I don't teach math and even though I teach programming, I don't really do polynomials in this way anymore so it's good to know that it's still in there.

[@gfetboi2515]

My teacher made me keep the parentheses and do this super complex version. Thanks for this, you probably saved me for tomorrow’s test.

[@OliviaBowers-mr4el]

Wow this helped me and made me understand so much thank you so much

[@MrCox-ev8zo]

Dude these vids help me Soo much my teacher sucks so these are a lifesaver Thank yiu

[@lana268]

I am from the US but I live in the philippines and don't speak bisaya. My teacher likes to start speaking bisaya when she is supposed to teach in English and I can never undestand. Tysm for this

[@bernardomiel1409]

0:56 I don’t get this very well? 5 out of something plus 2 out of something? Isn’t 5+2 = 6 ??

[@aspireanywhereanytimecoach8587]

Who gonna tell them?

[@chococandyplayz]

How can you even go to this lesson if you can't add right? 😭

[@OwlEyes198]

Omg Your awesome. But what did you do to the 13x? I'm confused

[@rysthan_jqp]

gigi blue he added the 13x to the difference of the 8x and 7x so the sum is 14.

[@SkyeBorgGames]

helped so much😢😢😢

[@RianJeanBerino]

My gosh thank you so much

[@inuyasha9475]

8+7=15 Boiiiiiiii😂😂😂😂😂😂😂😂

[@_official_Divyansh_yt]

you pagal

[@chococandyplayz]

8 - 7 + 13 dummy and he corrected 15 to 14 btw

[@lilvati]

my guy is going down in the history books

[@GavinLopez-gi1fs]

Thanks a lot, idk why school gotta Make it sound so much more complex and add more steps. Just stresses me out especially because my final math exam is tommorow

[@mhyaruffy3341]

OMG I GET IT NOW THANK YOU SM!

[@BeneluxMapperr]

Who is in class 1

[@stellaandybiersack9054]

THANKS THAT HELPED!!

[@yahyamalik06]

Thank you so much. I have a test tomorrow and my math teachers is so bad at explaining this video saved me from failing my exam😅

[@DaFan86]

He already is :) u can view his vids at any time

[@yaneeenmi]

thank you so much for this!! ❤️

[@kamalpreet1246]

Thankyou so much it’s is too easy to understand

[@JaxRaizenYT]

I got 14/30, awesome!

[@Oddestmonkey]

COOKING

[@amaiyajohnson1993]

I get that but one of my problem will be like (3x^2+5x+2)+(4x^3+2x-2)=ax^2+bx+c. How do I solve that?

[@nocturnalvisionmusic]

(3x^2+5x+2)+(4x^3+2x-2)=ax^2+bx+c Add like terms: 4x^3+3x^2+5x+2x+2-2 This would equal: 4x^3+3x^2+7x (+2-2 cancels out to zero) Factor out an x from 4x^3+3x^2+7x: x(4x^2+3x+7) Your ax^2+bx+c form final answer would be x(4x^2+3x+7). Eleven months later but I hope this helps anyone else who may need it :) (2/22/24)

[@baaznijjar1156]

thx khan academy

[@annaira3119]

Thank you so much

[@strangetothemax]

can you be my teacher?? forever?? please

[@hannahsyoutubechannel8394]

What is the simplest form of the answer?

[@theperson4yearsago565]

1:27 did bro swallow 🤨

[@scarfx6929]

Why would combine the answer on the 8x - 7x and the 13x?

[@vaeirian]

thsnk u i love u

if only my algebra2/trig teacher was good at explaining as you and i go to a private school for gods sake XD

[@KrizahRutchelle]

My school and this video had different explanations 😐

[@Ze9zz]

10 years ago?

[@yahyamalik06]

This video was made the year I was born in 2010 I’m 14 now 😭

[@michellexxrose]

I’m confused why the (+) isn’t distributed to the -7x in the second term, so it becomes 7x? If it was a subtraction between these two polynomials, the (-) would be distributed to all the coefficients but a (+) is not?! That doesn’t make sense!

[@jonwill]

You can think of distributing a (+1) if you like, but (+1) times a number is the number as it stands. It doesn't change the sign. +1(+) = same sign; +1(-) = same sign. Of course, as you correctly noted, if you distribute a (-1) the signs will change. -1(+) = change sign; -1(-) = change sign.

[@prettiecake]

@italianstallion929 Good Job random person

[@officialicey5690]

-7 + 8 + 13 = 15????
