Tet all those exparessions = T

\(a^2-b^2=(a-b)(a+b)\\ T=(a-b)T\\ so\\ a-b=1\\so\\a=1+b\\~\\ a+b=ab\\ 1+b+b=b(1+b)\\ 1+2b=b+b^2\\ b^2-b-1=0\\ b=\frac{-1\pm\sqrt{1+4}}{2}\\ b=\frac{-1+\sqrt{5}}{2}\\ b=\frac{\sqrt{5}-1}{2}\qquad a=\frac{\sqrt{5}+1}{2}\\ \text{But a and b are interchangeable so}\\ b=\frac{\sqrt{5}\pm1}{2}\ \)

You need to check it.

I am sorry catmg, I have no idea.

I do not understand the given answer and even the question is open to interpretation.

I assume there are 2 pairs of jokers where the members of the pair are identical but the pairs are different from each other? I don't think any other interpretation is likely so I guess I am being pedantic.

I would also like someone knowledgable to discuss this question.

If the last digit is zero then there are  ?   You answer

If the last digit is not zero then how many are there?

Add them together. 

GA is right catmg,

It's a good question.

It is best to just ignore rude trolls. 

They get bored and go away when they are ignored.  They can always find another site where they can get 'good' reactions :)

People here want feed back for their answers.

I am no exception.

I am not particularly comfortable with questions like this either but I think what I have done is correct.

I will just add the pics here

is is the second linked pic.

This question, or one very similar, was answered only a day or 2 ago.

Try looking for it.

I fond it, it is not identical but similar enough.

Mistakes like this are no big deal Builderboi.

I actually even think they are advanatgeous.

Questions askers should always chaek the answers they are given and this error was very easy to pick up.

The asker was obviously only interested in copying your answer into an answer box.

It is a positive thing that he got it wrong.
