| Trazmaball:
I already know how to put variables in, but whenever I do (4x+8)(4x-8) It just shows me -64 Instead of showing me 16x^2 - 64 So how do I get it to show the variables in the answer? |
| Xeda112358:
That requires a Computer Algebra System (CAS). I don't have that calc, so I am not aware of any CAS or symbolic manipulation programs for it. |
| TIfanx1999:
@Trazmaball X is being treated as a variable with a value. The calculator is just evaluating the expression based on what X is currently set to on your calculator. If you type X on the homescreen it will show you what the current value is. By default, I don't think the machine simplifies expressions like that. You would need a program that is capable of doing such a thing. |
