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.

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

@aksy6780 Год назад

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

@AbhinavKondapavuloori 6 месяцев назад

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..

@thethtwayaung82 24 дня назад

Much appreciated . I got it all now. It really hard for me when I take practice tests at school

@AbhinavKondapavuloori 6 месяцев назад

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

@michellez7245 3 года назад

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 3 года назад

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 3 года назад

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!

@diegomandragora4327 Год назад

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.

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

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.

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

@MathsKitchen 4 года назад

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