Thanks for the reply Alex. I think I understand that by choosing a
variable of the appropriate type, in this case one that is restricted
to the real numbers, the roots can be determined in a straight-forward
manner.

The way I see it, it is not actually a question about the variable
representing a real number; it is more a question of using polynomials
and their specialised built-in roots() method rather than symbolic
functions and the general-purpose

So I guess at this point my question is: is there another way to

The methods I used feel very hacky and I don't trust them.
Ok, so I think I found something in the manual
