Factoring with two variables



Greetings!
I am new to Internet listserv, and this is one of my assignments, to post
to a listserv. I am a new college student, and I just bought a TI-89 for my
math class. I tried factoring a problem like x^2-2xy+y^2, and what my
calculator displayed was x^2+y^2-2xy. Is there a way to get the calculator
to factor using two variables?

Thank you.
