Does it matter if you get it the other way round? e.g. (x+8)(x-5) for the last one?

Hi Jack, thank you for the video.

Is it neccesary to show solving a quadratic in A Level exams in other topics - say in mechanics? Often it comes as the final step of a longer procedure and it seems a waste of valuable time, especially considering it is not part of what is being tested in the question ie. you need to get to time / velocity. Would you say it is ok to just write the solution for time / velocity from our calculators?

Why cant I use +6x and -x in the first example?

Hi jack,
I was wondering if you were planning on doing any OCR MEI Mechanics 1 videos.
