    Isolating X....

    hey!

    I have to isolate x to find an inverse function of this....

    (x+2)^3(1-x)(3-x) = y

    ....

    x^5+2x^4-9x^3-22x^2+4x+24 = y

    I tried this...

    x(x^4+2x^3-9x^2-22x+4) = y-24

    but i just don't know what to do next

    can anyone help me??

    I think what you're asking for here isn't possible. Would you like to submit the original question, and then we could possibly suggest some alternative approach?
