RE: How to quickly solve a quadratic equation
Didier, what's the easiest way to enter those values? Do I create a matrix? I've tried using the [[]] template and deleting a set of brackets but it just returns an empty set of brackets. Also is the equation in the the form x^4 +2x^3 -25x^2 -26x +120=0?Finally, do you know of a way to quickly select the proot() command without searching through that entire list of commands in the toolbox catalog?

Tim, can you give me an example of how I would do what you suggested? If I wanted to find the roots for the above equation, how would I input it inside the parenthesis?

Sorry for the barrage of questions but my math knowledge is probably lacking compared to you guys and this is my first graphing calculator since a TI-83 in high school over 10 years ago.
