What is the product in simplest form? state any restrictions on the variable. y^2/y-3 * y^2-y-6/y^2+1y

Explanation:
When multiplying fractions, we multiply the numerators together and the denominator together and then we simplify.

The given expression is:


Let's consider the second fraction given:

We can do the following:
1- factor the numerator
2- take y as a common factor from the denominator
Doing this, we will end up with the following fraction:


The expression now became:


We can now multiply the numerators together and the denominator together as follows:
= 

Finally, we can note that we can perform the following on the resultant expression:
1- divide both the numerator and denominator by (y-3)
2- divide both the numerator and denominator by (y)
Doing this, we will end up with:


Since no further simplification can be done, therefore, our final expression is:


Hope this helps :)
