Can we appreciate the fact that this man has spent so much time and effort to explain this to us like we're babies learning for the first time with an empty mind? It makes it easy to learn step-by-step and understand the reason behind why we use different methods. You taught me this concept better than any other math teacher. Thank you.

[@MathsKitchen]

It's my pleasure. Glad it helped, and thank you for leaving such a nice comment!

[@HujinTF]

this is just shows teachers in real life vs teachers on the internet

[@aksy6780]

Explained this topic in 18 minutes 500 times better than my teacher did in an hour ❤

[@dillonpercy1058]

The x^2 - 9 was really helpful, I'm doing my MOCs soon so I really need to know this, thanks.

[@darcyagius5954]

Just gotta thank you for all the help because these question are in my year 9 exams and im reallt struggling with it. Thank you :)

[@MathsKitchen]

You're welcome, good luck with the exams!

[@gen7697]

Oml thanks for uploading this I was having trouble understanding when the equations were really complicated this helped me understand better ty so much!

[@MathsKitchen]

Thank you for the nice comment - glad it helped!

[@accountnotactive4248]

This is so easy wtf. My teacher makes it almost impossible. Props to you man

[@Nxgel1]

[@OHIOboss1st]

Thank you sir

[@user-gf8di7so5i]

Also cud u give a vid abt igcse exam revisions, including the imp. topics, things we need to practice more and outlining the main questions,would be really helpful for u

[@samraizali6862]

Wow it's beautiful mathematics

[@sienna4107]

better then my math teacher

[@suzietaylor6156]

Thank you, soooooo much for these clips. They have given me a lot of confidence with my studies.

[@LegendaryX3000]

hey how do we do (x+4)^4

[@user-gf8di7so5i]

thanks alot for the explanation...really helped...but cud u give us more advanced questions as im struggling with 10th grade igcse, and im in dire need of help...much appreciated if u cud give a link or upload a vid especially about quadratic equations,factorising and algebra..

[@bruhscout]

thanks so much you explain it very well

[@MathsKitchen]

You are welcome!

[@typicalgaminghd9401]

Thank you very much for this

[@MathsKitchen]

You're very welcome!

[@diegomandragora4327]

Is it still OK if I got the same two brackets, but my left side bracket and right side bracket were "swapped" compared to what's in the video? (X-5) (X+2) instead of (X+2) (x-5)? EDIT: Later in the video he says "it doesn't matter which side goes on the left and right as long as they are correct otherwise.

[@user-ee4qe6ez2j]

Hw to factorise 3a_3c

[@fahadcharaf1624]

thanks a bunch , i had a math's GSCE test

[@MathsKitchen]

You're welcome. Don't forget to practice over at my website Mathskitchen.com. And if you like it you'd be doing me a HUGE favour if you left a Google review here: g.page/r/CR_4rFf-RRfZEAg/review

[@srirachanoodles6914]

Thanks so much for this

[@MathsKitchen]

You're welcome!

[@DUALL3]

thanks Tr soomuch

[@MathsKitchen]

You're welcome!

[@evansnch]

Can you explain how to factorise with a prime number at the end such as 2q^2 + 7q +3? That would be great! Thanks for brilliant video.

[@kameroncarr8141]

no

[@xgeneralxahmad2426]

i would like to say thank you cuz i am having exams tomorrow so i was founding this topic a little bit harder but you made it very easy for me and also it saves my time

[@MathsKitchen]

Thanks for the nice comment, hope your exam was ok!

[@lalithprasanna8686]

Thank you 👍

[@MathsKitchen]

You're welcome!

[@BalwinderSingh-fh5ri]

I have this in year 8

[@rashedamalikali8120]

Wow, thank you so much for this. I'm helping my daughter revise and this has helped me to understand it so much better. I can now help her.

[@MathsKitchen]

That's brilliant. Thank you for the kind comment. Don't forget to head over to the mathskitchen.com website to keep practicing. And if you find it helpful it makes a huge difference if you can leave a review here: g.page/r/CR_4rFf-RRfZEAg/review

[@faizaanmehmood4608]

Can you do the questions where it involves something like 2x^2 + 5x +12

[@MathsKitchen]

Yes! It's on my list of ones to do very soon - should be up in about 3 weeks.

[@womendiaryofficial6589]

good😮😮

[@omarlagdel7971]

Wow you are amazing

[@MathsKitchen]

Thank you so much 😀

[@Rredrexx]

I have a text tmrw its a very important one , my teacher never taught us half the things that are going on in the test my teacher said it

[@metilaalam2462]

wish he was my school teacher

Crystal Clear - Highly Recommend….( My Tutor Made A Dog’s Dinner Of This.!!)

[@michellez7245]

hi! this is an amazing video! it explains very clearly and slowly. however, I’m still struggling to solve an equation on my own. can you help me solve 11k2 + 2k - 5 + 8k -k2 +9 . I wrote “2” where the exponents should be as I can’t type proper exponents. Thank you so much :D

[@MathsKitchen]

Hi Michelle, thank you - glad you liked the video. The general method with these is to simplify all the terms - in your case that gives 10k²+10k+4. You don't say what it is equal to. If it was equal to zero you could then simplify it further by halving everything. This gives 5k²+5k+2=0. You would then factorise or use the quadratic formula to solve. However, this equation doesn't have any roots so you wont be able to do that. Could you check the question to see if it was equal to zero or not? Thanks, James

[@jundong155]

I figured the answer I think. Its : 10k3+ 4 Just saying the "3" that I wrote is like an exponent but it doesn't allow me to type exponents so yeah!

[@user-vl5ih4nd8q]
