    Smile sove:(ax+b)/(cx+d) predigest this multinomial

    the answer is a/c+[(bc-ad)/c^2]*1/(x+d/c)
    but i couldn't solve the process.
    can you give me the detailed process?
    thank u

    It would appear the "predigestion" is long division?

    I'll give you a hint: how do you do the long division for the numbers 71/23?

    The short answer is "no." Simply because I hate typing in that "code" box. But I can provide you with a link (which process should be in your text anyway) that shows you the process.

    The first step (which is not commonly taken in most problems) in your problem is this:
    \frac{ax + b}{cx + d} = \frac{ax + b}{c \left ( x + \frac{d}{c} \right ) }

    = \frac{ \frac{1}{c} (ax + b)}{x + \frac{d}{c}}

    = \frac{\left ( \frac{a}{c} \right ) x + \frac{b}{c}}{x + \frac{d}{c}}

    Now do your long division.

    Now do your long division.
