This root has to be discarded as it would give rise to a

        negative number in a log. To confirm the results, again
        use SOLVE on your fx. The original equation is,


                      = log (2   − 9) + log (   − 1) − 2
                                                  2
                             2
        The keystrokes,


          w1i2$2Q(X)p9$+i2$
               J(X)p1$p2Q(=)0 q(SOLVE)


        Solve for X  1=



























        You can see the location where the function passes

        through the x-axis.
