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
Thorough presentation, well organized, cleared explanation, using the perfect light and colored markers optimize the learning process! Thumbs up!
Thank you so much!

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!
God bless you sir, I love your teachings.
Very interesting. I never knew math could be so sweet. Thank you very much.
The best explanation so far. Thank you Sir!
Math for myself, would have been a lot easier if we had TH-cam in the 90s.
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.
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.
you are the best teacher I've never had... =(
Great Explanation !!! Love it
Sir! Really great video it's very helpful
Please provide the link of your previous lecture in the description or the playlist link it will help a lot for new commmers
thank you for your teaching. Sir,
Great job. I follow you always. Maths is my food
Love the step by step process.
I wish u are my teacher
Why in the end of video, we do times to radical of 5?? Thanks
Sir, your teaching is very stylish indeed.....😍😍😍
😐🙄
thanks sir for this beautiful gift
I want to know how you solve problem 5}♤,
Thank you sir I love your teaching
Merci, j'aime beaucoup votre enseignement
I wish you're our Math Teacher
excelent info
THANK YOU... SIR...!!!
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.😊
Thank you buddy for your job.
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
¡Gracias!
Wow thank you so very much for the super thanks!
(5)(5)=25x2=50
Thank You!
(3)(3)=9x2=18
That trees are really cool stuff.
Excellent
square root used repeated factor number multiplication equation
Super Teacher!
I love mathematics, but I need someone to teach me deeply.
Same here
at 11:48 I get -2.radical 3 for the answer.
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.
I like you being a teacher.
y everybody saying math is so fun?
This awsome but it good
You're BADASS
Thanks. ❤❤❤
square root same divided
8/2=/50+/18
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?
Why radicals as a denominator is not acceptable??
Because mathematicians are picky and.don’t like it.
division used division multiplication subtraction
potatoes, buckets of potatoes.
Im in 9th d=grade right now I dont knowwwwwwwwwww
3/3+6/3
1.5
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.
(8)(8)=64x2=128
square root is equivalent of 2
/2+2/2
/49+1
9/3
add subtract radical
8/4
(4)(4)=16+2=18
(8)(8)=64+4=68

omit add positive sign not negative sign
