Re: Help! (Programming HP 39gs) Message #2 Posted by Gene Wright on 18 Sept 2008, 5:21 p.m., in response to message #1 by Anne
Go here:
39gs learning modules
You know have two approaches:
Approach 1: Use the builtin aplet on the 39gs called the quadratic explorer. It is shown in the PDF file for the working with aplets learning module. I highly recommend going this approach.
Approach 2:
Download the PDF file for the solving equations learning module.
Read through the module once downloaded.
Then go back and instead of entering the example shown on page 2 of the module (the example shown is v^2 = u^2  2ad), key in your quadratic equation. If the quadratic equation you're needing to solve is x^2 + 5x  6 = 0, then key in the equation and leave out the "= 0" portion.
Continue through the example in the learning module using the quadratic equation you entered.
Should be good to go.
