Rationalizing a Denominator

[@laurend8140]

Injecting humour into math goes a long way! thank you!

[@seangwapo9205]

Im not happy, not also sad Im depressed

[@nehalrohitclassix8848]

1)if you have learned the identity a^2-b^2 you can simplify the denominator without multiplying the WHOLE expression............--- this was for the first question that is root 2^2-1^2=2-1=1 2)and for the numerator you can use the identity (a+b)^2=a^2+b^2+2ab > this was for the second question hope this helps all of you for solving the question in an easier way

[@nehalrohitclassix8848]

and now you won't be depressed either😊

nice teaching skills

[@Heisenbergcooks619]

Lol after 6 years

[@vimbaimudzimba194]

Very well taught, easy to understand.Good job Sir

"Mathematicians don't like having square root as denominator" Me and intellectual who doesn't like having square roots anywhere: 😐

[@reineuwase1445]

Me who would rather have the square root below.

I have watched many of these videos and trying not to get sleepy.

NEHAL ROHIT CLASS IX thxs!

[@nishtarohitclassiii9653]

Hey you are welcome My pleasure😁😁

[@botshelopopiekomane8756]

the upper part is not a difference of two squares,its suppose to be root three plus root three,not root three minus root three

[@honey636]

did you watch the rest of the video?

[@ArvindYadav-dv4wi]

Yeah i just came to see the correction in comment....it will be √3+√3 so how one can cancel it though it is summation sign between them

[@botshelopopiekomane8756]

why did you cancel root three by the other?

[@botshelopopiekomane8756]

good,thought you wouldnt correct yourself

[@davidsmythe2223]

You can’t cancel terms with factors

[@labeebazainabreza8702]

i love you

[@lazolizs7683]

Gosh thanks so much!

[@moart87]

Thanks!!

[@alifdanial7495]

thank you!! this really helping

[@arunakumari1840]

I didn't understand the 3rd one Can you pls explain me again

[@عبادوعبادو-و8ص]

No😒

[@henryhowse9857]

ty

[@ttsookoo]

👏

[@AK-xi6nh]

{1+ squared root of 3}+{1+squared root of 3} don’t cancel

[@alannahkariuki1368]

can you be my math teacher pleaseeeee
