Ridiculously simple TI89 question

[tecrekka]

This is just driving me crazy, I know its a simple mode adjustment but I just can't find it. I am trying to display answers in algebraic notation but keep getting numbers that I can't even determine to base of.
Example: 3x^2(-5) yeilds -540 when I am looking for -15x^2.
If anyone could please help me with this exceedingly frustrating and exponentially benign question I would be grateful^10\inf.

Try F6 Clear a-z.

I can be wrong, but I guess you have defined x variable.

YEAH! That did it! Thank you so much. Now, how did I do that in the first place? Does the variable get set to a default when you define it in an equation? Just curious. You just made my whole semester, thank you so much!

I don't remember details, many ways to skin that cat. For example it is enough to STOre something into x. Like

2 STO> x

I see. Thanks again, I knew it had to be a simple solution but it eluded me for days.
