Factored form vs partial fraction form? I have already understood partial fraction and here is link for my relevant DSP SE question

Finding inverse z transform for two sided ROC?

But now i want to know, is there any difference between partial fraction form and factored form in signal processing context?

For example I have a z transform $$Y(z)=\frac{(z^2−z)}{(z^2+1.3z+0.3)}$$

a)What will be its partial fraction form?

b)What will be its factored form?
The partial fraction form helps in calculating the z-transform inverse since we can get the inverse of each term in partial fraction by inspection and hence get the inverse of the whole transfer function. The factored form can directly give poles and zeros by equating the numerator and denominator to zero.
