    Help with algebra - Fractions in simplest form

    Hi All,

    Been about ten years since I was in school and am now doing a maths refresher course externally. I am really really stuck on a problem:

    <br />
\frac{x}{x^2-1} - \frac{x+1}{x-1}<br />
    I would assume that the common denominator is x(x-1) therefore

    \frac{x}{x(x-1)} - \frac{x(x+1)}{x(x-1)}

    \frac{x-x(x+1)}{x(x-1)}

    That's where I get stuck. I'm sure it has something to do with the x-x(x+1)

    x-x^2+x maybe???


    Thanks guys (and gals),

    CHeers,

    J

    Hello .
    \frac{x}{x^2-1} - \frac{x+1}{x-1}=\frac{x}{{\color{red}(x-1)}(x+1)} - \frac{x+1}{\color{red}{x-1}}

    Did you catch it ? =)
