    My teacher told me I wouldn't be able to do all of a level maths in a year, your videos are the only thing that is allowing me to prove him wrong. You make maths so much easier than other teachers. Thanks for the great content!

      You can do it! You'll be extra proud of yourself when you prove him wrong. Keep it up!

    Hi Sir, I just wanted to say thank you for all the effort you put into your videos. I did first paper the other day but it didn't go to plan so I'm keeping focused on next week hoping it goes better. 🙏

      I’m sorry it didn’t go to plan, but I hope you’ll feel better about the next one! Good luck!

      That bit of the video is such a mess I’m sorry 😭
      Basically if you have -1/(x-1) and you multiply the numerator and denominator by -1 (remember multiplying fractions in this way doesn’t change them, they’re equivalent still), then you get 1/(1-x) which can be written as (1-x)^-1 which is then a pretty each binomial you work with!

    Sir, I personally like ASUS computers. If you are going to buy a laptop for your videos as you have mentioned it several times (not to buy a laptop) ASUS S14 or15 is one of best deals I think, you can have a look
    Thank you for helping Sir! My school maths teacher uses the same presentations to teach so its much easier for me to follow.

    hey for part a could you have done polynomial division please reply asap

    • @BicenMaths
      @BicenMaths  11 หลายเดือนก่อน

      No, this needs to be done as partial fractions, as the numerator is one degree lower than the denominator.

      You could do algebraic division too! This would also work, I just don’t love that method as much, so avoid it when I can. Try both ways!

    sir, why do you need to change the sign, can't you work keeping them meaning, can you write 1/x-1 as 1/-1+x and also for 4/x+2 as 4/2+x and work from there ,can you do that?
    Thank yous sir

    • @BicenMaths
      @BicenMaths  2 ปีที่แล้ว +2

      Yes you can do, but the formula for the Binomial expansion is written in the form (1+x)^n so I’m just wanting to mirror that form as closely as possible!
