AQ05a:

  1. See the introduction in Using the Symbolic Math Toolbox.
  2. See the description of subs in Symbolic Algebra.
  3. Here s is an algebraic equation, s(x). We are looking for the value of x that either sets s(x) = 0, or that makes s(x) a true statement. See Symbolic Algebra.
  4. The roots of a polynomial, f(x) are the values of x such that f(x) = 0. One function finds the roots explicitly, and another function shows an alternate form of f(x), such that the roots may be read from the equation. See Symbolic Algebra.
  5. This function just organizes the terms of a polynomial.

AQ05b:
