| |  distributing on Ti-84 plus
I am sure my calculator can do this, i just cant figure out how. For example, is there a way i can have the calculator work out [(6-x^2)^2-(6-4x+x^2)^2], to get the answer? |

You can either type out the word or pick it from your algebra or math menu.
Example:
expand((6-x^2)^2-(6-4x+x^2)^2)

(As you already have noticed the TI84 doesn't have the "expand(" command)
If you use a TI89 then you can use variables because this calculator has a CAS implemented. | | The following users thank earboth for this useful post: | | |

Yikes. I'm sorry for the bad information then. I thought the TI-84 was the lowest common denominator with the other algebra capable calculators.
Sorry Juggalomike. ;(
