how to check if two symbolic fractions are the same?

I have two fractions that have so many symbolic variables and are too complicated, but are in different forms. How can I check if they are equal to each other? For example:

syms x y z

fraction1 = (x+y)/(x*y) + z;
fraction2 = (x+y+x*y*z)/(x*y);

How can I check if fraction1 and fraction2 are the same?

Answer 1

syms x y z
fraction1 = (x+y)/(x*y) + z;
fraction2 = (x+y+x*y*z)/(x*y);
isAlways(fraction1==fraction2)

ans = logical

You can use isequal or isAlways, depending on the specific need. I suggest that you read the documentation, because there are nuances.
