[TI-M] Re: Polynomials, factors and division & 89/92+, SOLVED
I don't remember the exact equation, but I know it was a polynomial.
Polynomials can't be solved with matrices (at least as far as I know).
Also, the 82 doesn't have a CAS: it won't do something in terms of a
variable. One more thing: the 82 doesn't have a rref() function (stupid,
isn't it). You have to write a program on your own to solve matrices that
won't work with the ^-1 method.
