Find how many solutions this ln polinomial equation has

    2x^3lnx+x^2-4x+a=0
    [/tex]
    i thought of building a taylor series around 0 for ln
    but ln(0) is undefined

    I would find how many max min it has then knowing the each max min position I can determine the number of solutions.
    Take care of the x= 0 too.
