I have the Cambridge Pure Maths Exam on Tuesday and what I realized is that in a lot of the topics, you have to do some sort of factorizing. I used to be good at it but I completely forgot. This video helped me remember and I would like to say thanks a lot. If only every single Math teacher on the planet was like you ...
ahh thankyou so much! you are a genius! I have an exam tomorrow and I was stressing out because I had no idea how to do this. But you explained it perfectly! I hope you are a teacher because math teachers these days are terrible! haha. Once again, thankyou!
TheGennen the triple lines stand for being identical. The reason why he uses it here is because we're not dealing with an equation (finding x). we're just factorising. so you're now saying that the left is the same as the right but you don't know what the x values are. The special thing about the identical sign is that if you let x equal a value, let's say 0 and put 0=x on both sides, they'll both be equal. so triple line (identical) means all x values work equals (=) means not all x values can work e.g. 1/x=0 in this case, x cant equal 0 as it's undefined. so yeah, that's why he uses triple lines. it might be a bit confusing but you don't really need to worry about it unless you're doing more harder maths.

I watched so many videos on this subject and couldn't understand but i watched this and understood straight away. You truly have the gift of teaching.

Great teachers can take a concept that students often find difficult, simplify it and make it easy to understand. You are a great teacher, thank-you.
Thank you
Very kind, thanks
@aod412001 Thank you very much for your comments
@MegaHumanbean I am pleased to hear that this has helped you
The Multipilication method that he did was the FOIL(First Term, Outer Term, Inner Term, and Last Term) method
Oh my god you legend! Thankyou so much!
Your amazing if I wasn't subscribed to you I would be failing all my exams I don't understand anything in class only your techniques !
I wish you all the best then.
@prayersforremo I am a teacher but now teach maths privately
great tutorial !!!!!!!
@51smileyface Good luck - keep up the revision.
Why is he using triple lines instead of the regular = sign?

so triple line (identical) means all x values work
equals (=) means not all x values can work
e.g. 1/x=0
in this case, x cant equal 0 as it's undefined.
so yeah, that's why he uses triple lines.

Thanks, that actually makes a lot of sense. I'd just never come across the sign before!
is anyone watching this cause they do math methods?
