Multiply and Divide Rational Expressions
CAS Simplification
Try:
Simplify[(x^2 - 4)/(x + 2)]
Then:
Simplify[((x^2 - 4)/(x + 2)) * (x + 2)/(x + 3)]
Why does the result simplify this way? What terms cancel?

Try some Non-Trivial Factorizations
Simplify[((x^2 + 5x + 6)/(x^2 - 1)) * ((x - 1)/(x + 2))]
How does CAS handle common factors? Could this be used to verify student work?
