Get denominator with hold=True
t2=x.mul(1/(x^2-x),hold=True) t2.denominator()
results in x-1 instead of x*(x-1) or x^2-x. Is there any other way to obtain x^2-x?

To find out about the possible extra arguments of a method you could access its documentation with a question mark. Here
sage: t2.denominator?
Docstring:
Return the denominator of this symbolic expression
INPUT:
* "normalize" -- (default: "True") a boolean.
If "normalize" is "True", the expression is first normalized to
have it as a fraction before getting the denominator.
If "normalize" is "False", the expression is kept and if it is not
a quotient, then this will just return 1.
Hence in your situation you could do
sage: t2.denominator(normalize=False)
x^2 - x
