## TI-92 question

TPH recently posted a problem involving the expression

When I type this into my '92 it just sits there being "busy." All of my variables are cleared. Does anyone know what the calculator is trying to do here? It "hangs" for more than five minutes!

Thanks!

Same here. I would guess one of its simplification routines gets stuck in an infinite loop somewhere. I played around with it and it seems to hang on many similar expressions involving ratios of polynomials with variable coefficients, but those of second degree seem to work, and eliminating certain terms or replacing some of their coefficients with constant expressions often takes care of it. Oh well.
