Polynomials

Polynomial equations are discussed at Polynomials
and Roots, from the University of Saskatchewan's Exercises
in Math Readiness (EMR). The Advanced
Exercises require the solution of equations having radicals as coefficients,
and they also have a section on Graphing
Polynomial Functions
Or you can use our Graph
Explorer (or any Computer Algebra System or Graphing Calculator) to
graph polynomials that you may want to solve, and check that the x-intercepts
agree with what you have found by factoring or solving. You can also do
things like replacing x everywhere with (x+s) or with (x/r) to observe
the "shifting and scaling" properties that you may have learned about for
function graphs.

There is also a discussion
of polynomials at UBC in the intro to their on-line calculus course.

Our 'raw list' (of links provided without comment) may from time to
time include more examples
of material on polynomial functions if we do not have time to add them
here.

If you have come across any more good web-based illustrations
of these and related concepts,

please do let
us know and we will add them here.
