i still don't really get it... if the input is in shape of (ax+b)(cx+d) you can easily solve this to acx^2+x(ad+bc)+bd, which you can simply extract from your string looking at them as being just sequences of digits. i still think the problem is not defined well, for example can the input be (1+7)(15-3)?
if the input is in the above style you don't have to implement fancy parsing.
i guess this: acx^2+x(ad+bc)+bd solves 'adding the x'es'.

Well yes, That is easy. But i am trying to implement a function that will give me the output as a string and secondly will work for any sequence taking String as a parameter.
in your way , if i input (x-a)(x-b)(x-c)
You will not be getting the right answer right.
That is what i am willing to do.
Write a program that will multiply each of its term with the other terms and then generate a string as the answer.
