- polynomials are represented by lists using e.g., the prefix
operators PLUS for addition, DIFFERENCE for subtraction (or
unary MINUS), TIMES for multiplication and EXPT for
exponentiation; the first element of a list is the prefix
operator and the rest of the elements are its arguments
- the polynomial

- is represented by the list
`(PLUS (TIMES 4 (EXPT X 3) ) (TIMES 2 X) (MINUS 5) )` - this representation can be used for arbitrary algebraic
expressions
- algorithms using this representation are not particularly fast
