What are integral zeros, and can the TI-92 do anything with them? For example, this is my question: Determine the quartic f(x)=x^4+ax^3+bx^2+cx-c if it shares two distinct integral zeros with its derivative f '(x) and abc/=0. */= is not equal to. Can I graph integral zeros on a TI-92? I would appreciate any assistance, Michael
