You are correct. However, it is back to being correct on the next line as if I had of written x(x-3). I always do a worked solution before doing the video and must have miscopied this part. Thanks for pointing it out.
Amazing, you are a great teacher, you have helped so many students I'm sure, including me, I have a C3 exam tomorrow and I am going to go through all your tutorials today with no sleep, I am sure I will do well.
Does cross multiplying give you the wrong answer? Like if you do it for the last example? Because you wouldn't end up with a fraction if you did cross multiplication, but you get a fraction if you make a common denominator of (x-2)(x-1). You get different answers, so would the answer gained from cross-multiplying be wrong?
Hi there, I have a problem in a similar vein, and have tried to work it through using the method shown here, my problem is that I must use the quadratic formula on it and I can't seem to get it into the right format to do that. The problem is this: (3 / 2x - 3) - (2 / x + 1) = 5 How can I use the quadratic formula on this? Even once I have attempted to use the method in this video I am left with -x -3 / (2x-3)(x+1) = 5 and that doesn't work either. Any help would be much appreciated, thanks.
For C3 are you not missing the remainder theorem tutorial videos on your site cant seem to find anything similar?
Cheers
I have a CIE Add.Maths exam in a few hours ;( You're videos really helped!
I haven't done a tutorial by putting it across in the way you suggest.
Explained so nicely :)
7.20 shouldn't that fraction be multiplied by (x-3)?
You are correct, an annotation was added some time ago but you may have annotations switched off.
yay! now if only I can spot my own errors. good vids btw, they really help

Thank you! its very helpful :)
there is a mistake in your video. in the third fraction, it is supposed to be multiplied by (x - 3) instead of (x + 1). thank you for the help
I pretty much owe you a GCSE Maths A grade. Thanks! This is also helping with Maths AS level!
Once again you helped me to understand something that I had no clue in. You're brilliant at making stuff like this easy. Thanks a lot.

my hero
@omarkhan5 Wow, will make A-level students out of them yet. Thanks for your comment and support.

@pmaldinis Thanks - pleased to hear that.
@MrRyanification -1 is the same as + (-1), so multiply -1 (not 1) with the denominator, then add
Could you kindly make one on it please? Myself, and I'm sure many others, would appreciate it. It is an entire C3 chapter that hasn't been done.

can you help me please... how do you get the lowest possible dividend, the same denominator? in algebra, i understand common fratctions...
Amazing tutorial and so helpful thank you!
Clear and concise videos, quite helpful, thanks a lot.
Best explanation we’ve had! Thanks very much! We get it now😅
Cool
@plzdontkillme17 It's good to have your support, thanks.
Mans got the straightest lines
Thank you for this I was getting all confuse
@TheKoolkid619 Cool
Thank you!! you have saved me and my grades!
Well done
@MafiaCoder Best of luck but I think you need some sleep to do well.
@Triumphstag101 The answers are given as x = 1.76 or x = -1.36
Thanks alot! But if it came a question like 1/3y + 1/3x. PLZ Help me do that and give me extra information.
1 hour and 15 till exam
EdgEOf_DaRkNeSS All the best.
[iminent=UVJiqAgUWfOB] man thanks i owe you big time
The last part of the first step in example 2 is incorrect .... that fraction should be multiplied by x(x-3) not x(x+1)
Engineering student here😭 need this for first principal and partial fractions
To be honest I'm extremely confused, I don't understand it at all, is there not an easier way of this?
The method is good but not for beginners
how comes there is no division of polynomials or multiplying and dividing tutorial?? ExamSolutions
I haven't got round to doing those videos yet.
Arrrrgh hellllllp what if the expresssions are diffeeeent like x and Y ????
That doesn't matter
