Hi everyone,

I want to demonstrate that the equation has no fiber when x is a positive integer.

I am trying to calculate and I expect that i should get a negative square root (and thus demonstrate that it´s impossible).

But I don´t really know what to do with the negative sign that is before the square root.

Any idea?

thanks in advance..
