    Today was my maths calculator paper exam. It was for 2 hours. I realised back at home that I didn't do one big question (Graph of Functions). Like I didn't even touch it. I was planning on doing it last but Time went by so fast. I literally cried and didn't have the guts to tell my parents. Feedback day is going to be a nightmare. 😢. So I'm trying to do good in the non calculator paper and other subjects to at least get an overall A. Your videos has taught me a lot. Thank you for giving me hope in maths. You teach really wonderfully❤❤❤😊

      UPDATE: SHE FOUND OUT😭😭😭😭. My mom works at the school as a Account Teacher and she is CLOSE WITH MY TEACHERS. She just called (she was in school) and told me about the question. She was SO MAD😭. SHE SAID I LOST 20 MARKS!!!!!! Which isn't bad I think cuz it was out of 200 (the total marks). I'm scared for my life.

    @zarazoyalegoworld 5 месяцев назад +1

    For 4:04 can’t you just times the numerator and the denominator by 4 root 6 so like the denominator of the actual fraction? Or do we HAVE to times it by the sure and not the number

    • @1stClassMaths
      @1stClassMaths  5 месяцев назад +2

      You can do as you suggest but there is no need and you will then need to simply after by dividing it all by 4 again.

    • @deepaniliyanage4003
      @deepaniliyanage4003 5 месяцев назад +1

      No, because the 9 is attached by multiplication and the 3 is attached to the root by multiplication. Hope this is helpful

    For the last question and the last step, why can't you divide the 15 in the numerator by the denominator 15 so that you're left with 1, so your answer would just be -5root6

  • @chonk7650
    @chonk7650 9 месяцев назад +2

    Correct me if I’m wrong but I believe you could’ve simplified the last answer by cancelling out the 3s leaving you with - root 6

    • @1stClassMaths
      @1stClassMaths  9 месяцев назад +3

      Hi. You cannot do this I am afraid. If you want to divide by 3 you must divide all terms by 3 and you have not done the root6.
      The best way to avoid this mistake is only cancel if you can factorise out a common factor e.g.
      3x + 12 over 3y you can simply because it is 3(x + 4) over 3(y). Here you can see the 3 will cancel leaving (x + 4) over (y).

    I didn’t understand one thing. In the last example, why can’t we just cancel the 15 out and be left with (-5 sqt6)? Or cancel the 3 out and be left with (-sqt6)?

  • @iqra4523
    @iqra4523 5 месяцев назад +1

    for the last question, at the end all the three terms could be simplified by diving by 3, leaving us with -root2. Is that wrong to do?

    • @1stClassMaths
      @1stClassMaths  5 месяцев назад

      The 6 is inside the square root so you cannot do it like this. Only if there was a 3 before the square root.

      No just root 6. If we did 4root6 we would the need to simplify.
