So glad to hear that you have carried on to do A-Level maths and a huge congratulations on your grade 9, what an achievement!!! 🥳 I should have most if not all of the A-Level content done this year, I’ve got one more video to do and then chapter 4 will be complete, and I’ve done bits and bobs from all the other chapters, please do keep in touch and let me know how you are getting on, I’d love to hear!! 🙏🏽

    22:12 am I wrong in saying the x+2 for x and y was wrong? You put 1 2 3 5 7 but if it is x + 2 then 2+2=4 and 3+2=5 no? So it would be 12345 not 12357?

    • @JWP51015
      @JWP51015 5 หลายเดือนก่อน +3

      I hope i'm not too late but for this question, we would draw a quadratic graph for values of x. The video shows us solving for 2 values of x and these are the two points for where this graph intersects the x-axis.
      Since the original quadratic is greater than zero, we are looking for values of x that create a value greater than 0 when used in the formula. That means if you put a number smaller than -1/2 into the quadratic, you will get a number greater than 0. This new number is the value for Y on the graph.
      However, using numbers between -1/2 and 3 will give a value lower than 0 on the graph and will therefore, not be part of the set of values for x. This means the set for x must include all values below -1/2 and above 3 but not including the numbers between.
      Hope this helped!
