This depends on things you have not yet told us.

In particular -- what "standard algebraic notation"?  For x-squared: 
x**2 ?  or perhaps  x^2 ?  or something else like some Unicode 
characters or HTML to get a small superscript 2 above an x.

Once you give an example of what your input looks like, we can start 
hashing out how to read it.
