Algebra IIB – Multiplying Rational Expressions – some notes!

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.

Example 1

Algebra IIB – Multiplying Rational Expressions WS

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…

STATS – Regression Example Project

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.

Regression Test Project

Here’s the regression test project. This will be due the day of the quiz for bivariate data, on Friday, May20.

MATH 1050 – NEW ENTRANCE OPTION!

Hi everyone-

There is a new option for meeting the pre-req 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!

AP Stats – Practice Test

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.

The Exam Itself

To maximize your score on the AP Statistics Exam, you first need to know how the exam is organized and how it will be scored.

The AP Statistics Exam consists of two separate sections:

Section I 40 Multiple-Choice questions 90 minutes counts 50 percent of exam score

Algebra IIB – Solving Rational Equations, Example 3

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.

Algebra IIB – Example #2

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

Algebra IIB – Solving Rational equations – Example #1

I borrowed this from purplemath.com…

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
