# Unsure of denominator example C1 watch

1. Howdy .

I get how to do the attached method but does this only work when the denominators are in a certain form?
This is because I can answer questions that are in the form of the attached with no problems but it doesn't seem to work with other forms of denominator?

For example: Would it work if one denominator was (y-1) and the other (y-2) as I can't get it to work as I may be doing it wrong.

Attachment from my AQA book below.

Just to clarify: When can this method be used as it doesn't seem to work (if I am doing it right) on having denominators like (y - 1) and (y -2) etc.
2. . This can be simplified. I'm not too sure what your question is but I hope this example shows you if you're doing it right or not.

Hi, my question was can the attached method be used to solve questions with a denominator like (y-1) and (y-2).

So can you apply the method I attached to my original question, to the example you have just given?

Thanks

This pic is from my AQA book with the method that I mean ----->

I am trying to use this. Does that help?

Thanks for the help so far.

6. Don't know if this helps, op. It's a little mess I was in a rush

Edit: I wrote 2(3) instead of 5(3) by mistake, the rest of my working is correct though.

I think that for combining fractions all you need to know is that you always need a common denominator. That's it. Just make the denominators the same in any way you can and then combine. Then just cancel down your fractions.

I'm pretty sure AS exams are finished, a while ago actually.
