Hi,
I need help understanding how to implement a passage in my script. Here's what I'm talking about:
However, this method is limited to finding roots greater than 1, and will throw an error (ERR:NO SIGN CHG or ERR:DIVIDE BY 0) if it can't find such roots. By reversing the list of coefficients and taking the reciprocal of the roots found, you could find roots less than 1, but this would still result in errors if such roots don't exist either.

English is not my mother tongue and I'm a beginner at TI-Basic. I just need to know how "to reverse the list of coefficients" and if "taking the reciprocal" means (^(-1)) ?
Thanks for your time =)
