    its difficult to parse the question; can you rewrite it into something more discernable please?

    or use () paranthesis around stuff that is supposed to be grouped together? like perhaps: (x cubed over x squared) - (4 divided by x cubed - 9x) squared over (x squared + 7x) -18

    factor everything so you know what to cancel out; Also, take the bottom "fraction"; turn it over, spank it, and multiply it to the top "fraction"; like this: xxx (x+9)(x-2) --------- * ---------- (x-2)(x+2) xx (x-9)

    Now cancel like terms top tp bottom x(x+9) ---------- (x+2) (x-9)
