SUMMARY
The forum discussion addresses the "Not an Algebraic Expression" error encountered on the TI-89 graphing calculator when inputting the expression -1x/(x-1). Users suggest that the issue may stem from variable conflicts and recommend clearing variables or using alternative variable names such as y, z, t, or xy. The TI-84 calculator successfully processes the same expression, indicating a difference in handling algebraic expressions between the two models.
