You can get around the +/- by using a list.  Do this:

(-b + {1, -1} sqrt(b^2-4ac))/(2a)

To store the formula...hmmmm...I've sold my 85 and have also lost some
of my knowledge of it.  I believe you can type in the formula (given
above) type in the equal sign and then the name.  for example:

(-b + {1, -1} sqrt(b^2-4ac))/(2a) = QF

If I'm wrong about this then somebody please correct me.
