Notice the picture above, the "diameter" is 4.3, meaning its radius is half that, or 2.15, and it has a height of 4.7.
We start with
We can factor x at the numerator:
So, assuming (otherwise the expression would make no sense) we can simplify it:
This equation has no roots, so we can't simplify it any further.
