which -i believe- is the same as:
...and basicly this is status quo, because this is, with what i have spent the last hours. i feel pleased for any answers or recommentations: this might be a trivial problem for some of you, but not for me! It's a shame, that i probably have problems with some very basic mathematical operations. please help me!
I really tried hard, but this really starts to make me sad, because i am not able to understand your answers. my problem seems to be more fundamental than i ever thought. thanks for your advise!
As I understand the hint, that "the LCM of (2n+1)*(2n+3) and 2n+1 is (2n+1)*(2n+3), not (2n+1)*(2n+1)*(2n+3)":
Let me assume, that
so, that for
which leads me to:
what's wrong about?
i could not find a good source, which describes how to factor out something works yet. I believe this is, why i cannot see why
