Multiplying and Dividing Rational Expressions
Multiplying rational expressions is similar to multiplying fractions in arithmetic.
Procedure
To Multiply Rational Expressions
Step 1 Factor the numerators and denominators.
Step 2 Cancel all pairs of factors common to the numerators and denominators.
Step 3 Multiply the numerators, and then multiply the denominators.

By adick, on May 19th, 2011 Today you received the last assignment of the year! We worked on simplifying/multiplying rational expressions, and will have a quiz on that material on Monday – Be Prepared! Here is the worksheet you received…
By adick, on May 18th, 2011 OK, sorry it took me a bit, but here is an example of teh regression project. Remember, I need to see al the components of the project description for full credit.
By adick, on May 18th, 2011 Here’s the regression test project. This will be due the day of the quiz for bivariate data, on Friday, May20.

By adick, on May 16th, 2011 Hi everyone
There is a new option for meeting the prereq for Math 1050, as of a few days ago. Students may now take a MATH 1010 final in lieu of the ACT or Accuplacer. This is a free option which can be used once per term per student, but must be administered by the . . . → Read More: MATH 1050 – NEW ENTRANCE OPTION!
By adick, on May 10th, 2011 OOPS! I just realized, as I was browsing the material on AP Central, that it is prohibited to me to post that practice test online. I apologize for my oversight. However, if you want to come in tomorrow morning and look at it and its solutions,I’ll be here.

By adick, on May 3rd, 2011 Solve the equation: Since this is a CUBE root, rather than a square root, I undo the radical by cubing both sides of the equations, rather than squaring:
I must remember to check my solution:
3 = 3 …yes!
So the solution is x = 16.

By adick, on May 3rd, 2011 Find the solution: <== (wrong!)
This already has the square root by itself on one side, so I can proceed directly to squaring both sides. However, a great many students will do the following when given this type of question: This already has the square root by itself on one side, so I can . . . → Read More: Algebra IIB – Example #2

Solve the equation:
I could square both sides now, but look what I would get:
So, while squaring both sides at this point would not be “wrong”, it would not be the most useful first step. Instead of squaring right away, I will first move the 2 over to the . . . → Read More: Algebra IIB – Solving Rational equations – Example #1
