In this lesson, you will learn how to add and subtract radical expressions in algebra. We must learn that in order to add radicals, the radicals must match exactly along with what is under the radical.
We will practice adding radicals and subtracting radical expressions by solving problems. We must always try and simplify the result and rationalize any denominators present.
Never knew radicals was this is easy. Can't believe i cried over these on 9th grade LOL. Great explanation thanks!
llort evol you’re not the only one 🤦♂️😭
I hope y’all are right i go in to 9th grade in August
I'm crying over here in 7th grade
Ugh I am in 9th grade right now I hope this helps because I am the worst at algebra!!😭😰
imagine being good at algebra LOL
Best teacher ever since creation of internet.
As a mom of a student being in Honor Algebra, I can only thank you for an amazing explanation!
Thorough presentation, well organized, cleared explanation, using the perfect light and colored markers optimize the learning process! Thumbs up!
Thank you so much!

God bless you sir, I love your teachings.
The best explanation so far. Thank you Sir!
Very interesting. I never knew math could be so sweet. Thank you very much.
THANK YOU SO MUCH SIR,
for make this video free it is really helpful to clear our doubt.
Amazing Math Just become so simple for me. Thank you so much Sir.
You are awesome helping me alot on remembering basics as I am preparing for GRE exam.
thanks so much for sharing your math help so much. and you have it easy to under stand.
Love the step by step process.
I wish u are my teacher
you are the best teacher I've never had... =(
Math for myself, would have been a lot easier if we had UA-cam in the 90s.
thank you for your teaching. Sir,
Thank you very much, this teacher is very clear big helper to me I my teachers will like will like to know.Thank you again.
Great Explanation !!! Love it
Please provide the link of your previous lecture in the description or the playlist link it will help a lot for new commmers
Sir! Really great video it's very helpful
Great job. I follow you always. Maths is my food
thanks sir for this beautiful gift
THANK YOU... SIR...!!!
¡Gracias!
Wow thank you so very much for the super thanks!
Thank you sir I love your teaching
Merci, j'aime beaucoup votre enseignement
Sir, your teaching is very stylish indeed.....😍😍😍
😐🙄
I wish you're our Math Teacher
Thank You!
Thank you buddy for your job.
I need to see some examples with variables in the root. Great help though
Variables would be no different. As long as the variables are the same, they can be added.
Thanks. ❤❤❤
Super Teacher!
Why in the end of video, we do times to radical of 5?? Thanks
excelent info
Excellent
This awsome but it good
That trees are really cool stuff.
I want to know how you solve problem 5}♤,
What do you do if you have no extra prime in the prime factor tree? Since if there was an extra, you put them as the radicand. But if there's no extra, what then? I'm trying to solve 2 times cube root of 27 and doing the prime factor tree of 27 is 9 times 3 and 9 becomes 3 times 3. Since it's the cube root, I need triplets. All the 3's in the prime factor tree of 27 has now become one and I have no more extra. Please help asap thank you!
Sometimes the radical goes away. Sorry I know this way too late. But in this case you just end up with 6. As it’s 2* the cube root of 27, which is 3. Meaning the remaining problem is 2*3. Which we all know is equal to 6.😊
You're BADASS
(5)(5)=25x2=50
at 11:48 I get -2.radical 3 for the answer.
I like you being a teacher.
(3)(3)=9x2=18
square root used repeated factor number multiplication equation
square root same divided
1.5
Sir , when we take another multiplication of these radicals it's getting another answer, I meant for an instance if we have √36, you got 6.6, but if we take 9.4 then our answers will be wrong, isn't it
I meant 16.55 min part question
√36 is a perfect square;
You could do √9×4 but think about it
√9 × √4 = 3×2
3×2 = 6
The answer is still the same.
@@marcui_louie thank you

8/2=/50+/18
/2+2/2

division used division multiplication subtraction
y everybody saying math is so fun?

add subtract radical

I love mathematics, but I need someone to teach me deeply.
Same here
(8)(8)=64x2=128
(4)(4)=16+2=18
/18

(2)(2)
(8)(8)=64+4=68
/2
Why radicals as a denominator is not acceptable??
Because mathematicians are picky and.don’t like it.

Im in 9th d=grade right now I dont knowwwwwwwwwww
square root is equivalent of 2
2x+y
/16+2
7/1
The square root of 32 is 16, you could’ve just done 16 because 16 + 16.

Why not provide a link to the videos you’re referencing. Not that difficult to do.
Why dont you do it?
8/2
68=/68
8/4=/50+18
/50
2 4 6 8 9 10
omit add positive sign not negative sign
in what country the radical sign is written that way? so confusing.
Sometimes people will put a downward stroke at the end of the sign to make it clear what is included underneath the sign and what is not. I personally don't write it that way, and I'm American, as I'm assuming this man is based on his accent. I don't think it's a country thing, just a personal preference thing, similar to handwriting.

math will be is when you know what you are doing
divided
square root repeated equation
cannot be
hahahaha
