Week 1 First Messages

What four steps should be used in evaluating expressions? Can these steps be
skipped or rearranged? Explain your answers.

Do you always use the property of distribution when multiplying monomials
and polynomials? Explain why or why not. In what situations would
distribution become important?

Imagine your younger relative--of middle school age--was taking an algebra
course and asked for your help. How would you teach the multiplication of
polynomials to her?
Week 2 First Messages

What is the greatest common factor? How do you know when you have found
the greatest one?

Explain how to factor the following trinomials
forms: x2 + bx + c and ax2 + bx + c. Is there more than one way to factor this?
Show your answer using both words and mathematical notation.

How do you factor the difference of two squares? How do you factor the
perfect square trinomial? How do you factor the sum and difference of two
cubes? Which of these three makes the most sense to you? Explain why.

What one area from the readings in Week Two are you most comfortable
with? Why do you think that is? Using what you know about this area, create
a discussion question that would trigger a discussion--that is, so there is no
single correct answer to the question.


Explain the five steps for solving rational equations. Can any of these steps be
eliminated? Can the order of these steps be changed? Would you add any
steps to make rational equations easier to complete or understand?

Do all rational equations have a single solution? Why is that so?

What constitutes a rational expression? How would you explain this concept
to someone unfamiliar with it?

How would you define what a rational exponent is? Is there such a thing as
an irrational exponent? Explain.

What are the two steps for simplifying radicals? Can either step be deleted? If
you could add a step that might make simplifying radicals easier or easier to
understand, what step would you add?


Explain the four steps for solving quadratic equations. Can any of these steps
be eliminated? Can the order of these steps be changed? Would you add any
steps to make solving quadratic equations easier or easier to understand?

Which of the four operations on functions do you think is the easiest to
perform? What is the most difficult? Explain why.

Write a word problem involving a quadratic function. How would you explain
the steps in finding the solution to someone not in this class?

Is the compound interest formula--such as would be used to calculate a car
loan--an example of a function? If yes, of what type of function is it an
example? Why might you identify it with that type of function?

What is the relationship between exponents and logarithms? How would you
distinguish between the two, using both a graph and a sequence?

How are these concepts of direct, inverse, and joint variation used in
everyday life? Provide examples for each.

Other than those listed in the text, how might the Pythagorean theorem be
used in everyday life? Provide examples of each.

Quadratic equations, which are expressed in the form of ax2 + bx + c = 0,
where a does not equal 0, may have how many solutions? Explain why.

What is the quadratic formula? What is it used for? Provide a useful example
that is not found in the text.


From the concepts you have learned in this course, provide a real-world
application of something that you think has been the most valuable to you?
Why has it been valuable?

How do you think you will use the information you learned in this course in
the future? Which concepts will be most important to you? Explain why.
Which do you anticipate will be the least important? Explain why.

Can you think of one real-world example of when the concept of functions
might be useful? Do you think you will ever use functions in your life to solve
problems? If yes, explain how and why; if no, explain why not.

What one concept learned in this course was the easiest for you to grasp?
Why do you think it was easy for you? Which was the hardest? What would
have made that hard-to-learn concept easier to learn?

If your neighbor asked you to explain what you learned in this course, what
would you tell him or her?
