Week 6 Attendance Quiz Hints
-----------------------------

**AQ05a:**

#. See the introduction in :ref:`symbolic`. 

#. See the description of ``subs`` in :ref:`symAlg`.

#. Here ``s`` is an algebraic equation, :math:`s(x)`. We are looking for the
   value of :math:`x` that either sets :math:`s(x) = 0`, or that makes
   :math:`s(x)` a true statement. See :ref:`symAlg`.

#. The roots of a polynomial, :math:`f(x)` are the values of :math:`x` 
   such that :math:`f(x) = 0`. One function finds the roots explicitly, and
   another function shows an alternate form of :math:`f(x)`, such that the roots
   may be read from the equation. See :ref:`symAlg`.

#. This function just organizes the terms of a polynomial.

**AQ05b:**

#. Read the function descriptions in :ref:`symAlg`.

#. Read the function descriptions in :ref:`symAlg`.

#. Read the function descriptions in :ref:`symAlg`.

#. See :ref:`symDerivatve`.
