Extraneous solutions, absolute value

Hi Forum!

I've just found something strange

*The closest integral of sum of the solutions to * * is*

OK, calculating, we get two solutions

and

But the solution says that should be disconsidered.

Why?

The sum of them would give something about .

Can someone explain?

Does makes the function diverge?

Thanks

Hi Prove It

I get your point, then it is necessary to test the values.

I thought there was something else to it; this is really simple. :)

Thanks for your reply.

All the best.
