Algebra Math Help

I have a TI-84 Plus Silver Edition and I want to download apps/programs?

so today in algebra, my teacher gave all of us the Quadratic Formula program by hooking it onto her calculator. And she said we could find more programs (like perfect cubes and whatnot) on the website to download but I cannot find them. Can someone please help me find the programs to download!

You can search through this for programs. Need TI Connect (free download) to transfer the program though.
