**AND**

**Step 3: If needed, simplify
the rational expression.**

***Divide out a common factor of y**

***Excluded values of the original den.**

Note that **the values that would be excluded from the domain are
0 and -1/2.** These are the **values that make the original denominators
equal to 0**.

Putting all the different factors together and using the highest exponent,
we get **the following LCD** for all the small fractions:

***Factor the GCF of 2**

***No common factors to divide out**

***Excluded values of the original den.**

Note that **the values that would be excluded from the domain are
0, -3 and -7/2.** These are the **values that make the original
denominators equal to 0**.
