    ill be real, this might be the only topic in maths where the teacher actually explained it well to me, since this was the only way to solve the quadratic equation, other than that you taught me the rest of maths very well.

    Hi I'm quiet confused with the sum at 15:47 because in the cgp revision book it says if either a or c is negative, the -4ac becomes +4ac so in this sum c=-13 but you didn't write it as +4ac as it says it should be done like this in the book please can you clarify this..

  • @Sportcat01
    @Sportcat01 3 ปีที่แล้ว +1

    Will you sometimes have to rearrange it in that form ax^2 + bx+ c for the quadratic formula to work if it isn’t in that form already?

    • @TheGCSEMathsTutor
      @TheGCSEMathsTutor  3 ปีที่แล้ว

      Absolutely! Most of the time you will need to rearrange a quadratic that has been formed, like in probability equations for example, check that one out! 😁
