    I tried your link. I didn't get any equation, just some fraction. Maybe the link is defective.

    Okay, so it is a fraction, but how do I simplify it.

    These are the options?

    you want to multiply the numerator by the reciprocal of the denominator.
    To do that, begin by writing the number 1 as the ratio of (x - 2) to its self.
    That is , writing
    1 = (x - 2) / (x - 2) in the first term


    and


    1 = (x + 2) / (x + 2) in the second term

    will help a lot.

    I got (z^2)/(9x^8)

    For the latter one:
    Just multiply it by itself, simplify that by collecting coefficients if you can, then put it beneath a one.
    You could then simplify or express as a partial fraction as necessary.
