Getting Fractions on TI Nspire CX - Eigenvectors & Polynomial Roots

[Klause]

Hey so I'm new to my TI nspire cx, still getting the hang of it. I've been trying to figure out how to get my eigenvector values to be fractions instead of decimals when I calculate them on here. Also, when I find the polynomial roots I get back decimals instead of fractions. I would like to know how to get back fractions instead for both cases. I've fiddled with a few things in the settings, but no luck.
Any help would be appreciated.
Cheers!

You download the library, install it, and use the function as shown in the GIF.

Although I don't know if it works for eigenvector values.
