    This is actually a fairly easy program to write and a good exercise in BASIC, or something similar which the TI-83 uses. I don't have one in front of me, but I'll try to remember the syntax from memory - it might a little off.

    ClearHome
    Disp "Ax^2+Bx+C"
    Input A
    Input B
    Input C
    If sqrt{B^2-4AC}<0
    Then
    Disp "Non-real answer"
    End
    Else
    sqrt{B^2-4AC} -> D
    (-B+D)/(2A) -> M
    (-B-D)/(2A) -> N
    Disp "Roots are:"
    Disp M->DispFrac
    Disp N->DispFrac
    End

    That's the idea of it, probably with a lot of errors though. Just having some fun.

    Have a look here: http://www.mathhelpforum.com/math-he...-equation.html

    If you want to get the real solutions only you still can use the SOLVER of the TI83: MATH 0: SOLVER

    The best way to solve an equation (I believe) is to graph it up and find the x-intercept. The Ti-83 allow you to find zeros in the graph mode.
