Simplifying (xy)/(xz)

[saenbateman]

I've just got the ti-89 and it seems to automatically simplify most other things but when I try to get (xy)/(xz) to simplify to y/z it doesn't do it


Where am I going wrong guys?

[Dave X]

thats quite easy, as you are entering xy and xz, which your calculator recognizes as one variable, not multiplication
beware of juxtapositions, they can lead to wrong results

type (x*y)/(x*z) and the calculator shows correct result
