Check answers of rational expressions

Hi,

I am in an Algebra II class. I already took it years ago, but I am taking it again as a refresher. I have done two problems that I uploaded for this community to check to see if I have the right answer. I wrote out the whole equation. This will probably be very easy for the members here.

1.) This is a subtraction and simplifying of a rational expression.

2.) This is a find the domain problem...
