# Get denominator with hold=True

I am struggling to get the denominator of an expression defined with `hold=True`

.

The expression is a quotient with a common factor in the numerator and denominator.

I don't want the common factor to be cleared out.

Example:

```
sage: t2 = x.mul(1 / (x^2 - x), hold=True)
sage: t2
x/(x^2 - x)
sage: t2.denominator()
x - 1
```

This results in `x - 1`

instead of `x*(x - 1)`

or `x^2 - x`

.

Is there any other way to obtain `x^2 - x`

?
