    Complete the operation and simplify

    Couldn't get the LaTex to work, so here it is:

    (3+1/x) / (3-1/x)

    [tex]\dfrac{3+\frac{1}{x}}{3-\frac{1}{x}} [/tex] gives  \dfrac{3+\frac{1}{x}}{3-\frac{1}{x}}

    \displaystyle \frac{3 + \frac{1}{x}}{3 - \frac{1}{x}} = \frac{\frac{3x + 1}{x}}{\frac{3x - 1}{x}}

    \displaystyle = \frac{3x + 1}{3x - 1}

    \displaystyle = \frac{3x - 1 + 2}{3x - 1}

    \displaystyle = 1 + \frac{2}{3x - 1}.


    Pick whichever form you think is "simplest".

    Thanks.

    Looks like on the LaTex in LyX that would take a display fraction rather than a standard fraction.
