Problema Solution
How is doing operations (adding, subtracting, multiplying, and dividing) with rational expressions similar to or different from doing operations with fractions? Can understanding how to work with one kind of problem help understand how to work another type?

It is similar to doing these operations with fractions. You need to find the LCD between the two rational expressions if they are added or subtracted from one another.
If it is multiplied, do all the simplifying RIGHT IN THE BEGINNING before the factoring become too complicated. rationalizing rational expressions HAS A LOT OF FACTORING!!!
if you are dividing the expressions, take the second and just flip it upside down and multiply them then. and remember. simplify before multiplying, adding, or subtracting. it'll make ur life a lot easier.
this will never be used in real life.
