I am needing help, not sure how this can be done. I have a TI-89 Titanium. I am needing to know how to factor equations with more than one variable...i.e.)

12x^2-17xy+6y^2

Any help is great!

Thanks!

The same way you factor expressions with one variable:

>factor(12x^2-17x*y+6y^2)

(3*x - 2*y)*(4*x - 3*y)Just make sure that you write x*y and not xy. The first is the product of x and y, but the second is the single variable named "xy." The factor() function can be found in the Algebra menu (F2->2 on the home screen).
