#### Answer

$z(z-2)$

#### Work Step by Step

We are given the denominators $z-2$ and $z$. In order to find the least common denominator, we must factor each denominator. $z-2$ cannot be simplified further $z$ cannot be simplified further Next, we multiply together all distinct factors from each denominator, with each factor raised to the greatest power that occurs in any denominator. $LCD=z\times(z-2)=z(z-2)$
