I was looking at curve25519 and notice that it's starting parameter is x=9
I read that, but what is 'a' exactly? If it is an unknown constant, then how will I find when the said result will occur. Is it 1? Or does the value of a has no impact on the result (but it certainly does)? Or on calculation the value of 'a' will be given?
I think I did not understand the question properly.

That I cannot answer. I'm currently doing some reading on the curves and trying to see what I can get out of it. (so far not much

)
