I am currently struggling in math because of today's online classes due to this covid... this video helped me a lot and I want to thank Khan Academy for this... Love from the Philippines!

Thanks! I'm in 9th and I'm in algebra 2 honors, and my teacher doesn't describe the lesson well this helps a lot! *subscribe* you make it easyer to understand! Precal and algebra 1 for collage here i come! (Nxt year) ;-; ~tear

Extremely helpful, thanks a bunch

This is extremely helpful for me. Even though im just grade 8, the teach me the topics of 9th or 10th. While my sir was teaching, I couldnt understand. But now I can see everything coming together. Very very thank you❤

for the bottom equation, the one that your dividing by all your doing is finding the zero of it/roots so basically X+4 is X+4=0, that's why it is -4 and if you graph y=x+4 the root aka x-int is -4 same if you divide the polynomial by x^2-1, you find the zeros which are 1 and -1 and use it for the synthetic division(same place the -4 was put in the videos example)

I've always heard, "Set (x + 4) = 0" But same concept, same result using the negative of 4 ( -4 )

Im an 8th grader and we are doing this in Pre Ap Algebra 1 i didnt get it when my teacher explained it so so but this helped a lot thanks

Ah, thanks so much! Kahn Academy is awesome!

This has saved me from having the most miserable night of precalc in my life. Many thanks!

Thank you sooo much.It help alot

Thank you so much. You explained it better than my teacher.

10 questions 1. Are you sure you cant do it with coefficient? do you know binary?

yow! thanks so much it will soon help in my ft tomorrow because i got zero on my 2 ft hopefully it will develop my score

this is so much easier than long division with polynomials

Thank you

Ma Sha Allah. Nice. Thanks.

I prefer traditional long division but I had a problem that it didn't work for. Please tell me if i am making simple mistakes or synthetic only works for this problem. PROBLEM: (x⁴−3x³+x-4)(x+1)

I also prefer normal long division, even for polynomials. But I haven't seen the synthetic division before. :)

GOD job thanks

This video is very helpful especially for me because we are just in 8th grade but we are already studying about thism

Thanks!!! For a really effective explaination.. I think I finally understood something in math😂😂😂.

Great video!

but what part is the remainder and what part is the quotient? the remainder would be the last term on the bottom right? and then would the quotient just be the original x-a term?

So what if the bottom is already a negative, do you keep it as is or change the sign to positive?

Really nice....sir

thanks sal

pure magic

I hope that this video is more helpful then the other video.

Dude! what method are you using?

Thank u so much....i have an exam today..

Sir please make a video or tell me the derivation of synthetic divsion

you da man thanks

Great video

Nice.

i love ur language...cool

WOOWW BUT THE NEGATIVE IS CONFUSING ME

Thanks

does he have a video of the extra bells and whistles required to do this when the coefficient of your divisor isn't 1?

America: its so hard Philippine: u Sure about that

At the start what if it's already negative do we change it into positive

Question.. why do you change the +4 on the bottom to a negative in dividing?

@ogzelle

Britney Campbell You set it equal to zero, x+4=0, subtract 4 from both sides, *boom* you get -4

Yee thank you ShakaKHAN

Thanks I get it noa

my dad made me learn this over summer break. and im in 7th grade. and ive forgotten already.

I have one question sal at 2:28 is there a reason why u have to take the negative?

IT IS VOOOOOODOOOOOO!!

do synthetic division with numerical coeficient do it if its no voodo magic!!! #dooksrR'us

Anyone else wonder how his handwriting is so good?

But why is the 4 negative?

My mind just got fucking blown.

Who invented this, long division makes so much more sense in my opinion

So the last term is always the remainder?

I am 9 years old. Why is this in my recommendations.

LOL I can't stop laughing, that's exactly what I thought.

Holy shit, Mind Blown.

All my math teachers got confused when I used synthetic division. I just felt the "traditional" way took up way too much space.

What happens if the bottom is 2x +8?

i hate online classes...

Hey, I don't understand you said there would be square 3 but where is the x coming from?, should I just follow that without any reason? please help.

@JamesTownsendJian

8 жыл бұрын

The 3 itself isn't getting squared. It's the X that's getting squared. After setting aside the remainder, you start with the constant (30) and take it from there by increasing the power by one as you move from the right to the left. So you have 30, then -8x (or -8x^1), then 3x^2. If he had ended up with more numbers, the powers would keep increasing by one. So for example, and this is only an example mind, assume he'd ended up with 8, 5, 3, -8, 30 and -121. In this case, he would set aside the -121 as the remainder and again start on 30. That would be 8x^4, 5x^3, 3x^2, -8x and 30. I hope this helped. :)

Sal to the rescue

I am so stress about our test tomorrow because i don't know how to do it.
