    You've asked in the introductory physics forum rather than the math one, so you must expect to get a practical answer rather than a nice mathematical one! I suggest you type it into the grapher at
    and it will show you where the zero is.

    Turns out. I didn't need it. After I figured out the co-ords of the two stationary points and what happens when X gets inf and -inf then I could see what the roots were and according two the graphics I drew it's about 3.14 so I am pretty sure I didn't have to factorise that damned equation.
