For the problems on page 345-6, factor the polynomials using whatever strategy seems appropriate. State what methods you will use and then demonstrate the methods on your problems, explaining the process as you go. Discuss any particular challenges those particular polynomials posed for the factoring.For the problem on page 353 make sure you use the “ac method” regardless of what the book’s directions say. Show the steps of this method in your work in a similar manner as how the book shows it in examples.Incorporate the following five math vocabulary words into your discussion. Use bold font to emphasize the words in your writing (Do not write definitions for the words; use them appropriately in sentences describing your math work.):Factor  GCF  Prime factors  Perfect square Grouping

Your initial post should be 150-250 words in length. Respond to at least two of your classmates’ posts by Day 7. Make sure you choose people who don’t have the same numbers as you worked.  Do you agree with how they used the vocabulary?  Is their example of polynomial multiplication suitable as a comparison?

Inequalities

Read the following instructions in order to complete this assignment, and review the exampleow to complete the math required for this assignment:

Read the article about Body Mass Index (BMI) on page 151 of Elementary and Intermediate Algebra. Use the formula given using pounds and inches for finding the BMI at the end of the first paragraph in order to find the four intervals the article mentions:17 < BMI < 22 might have a longer life span than average23 < BMI < 25 probably not overweight25 < BMI < 29.9 probably overweightBMI > 30 obese

You will use your height to plug into the formula to solve for W, the weight range that will go with each category. You may prefer to solve the formula for the variable W before plugging in values, which is fine.

Write a two to three page paper that is formatted in APA style and according to the Math Writing Guide. Format your math work as shown in the Instructor Guidance and be concise in your reasoning. In the body of your essay, please make sure to include:Your solution to the above problem, making sure to include all mathematical workA discussion on the computed weight ranges and some reasons why they could be misleadingAn evaluation of the regions outside of the “probably not overweight” range using both set notation and interval notation. Include a simple graph of the regions. (See Instructor Guidance example for some ideas of how to do this.)The incorporation of the following five math vocabulary words into your discussion. Use bold font to emphasize the words in your writing (Do not write definitions for the words; but integrate them into your discussion.):InequalityEquivalentCompound inequalityIntervalInfinity

Financial Polynomials

Read the following instructions in order to complete this assignment, and review the example of how to complete the math required for this assignment:

1         Solve problem 90 on page 304 of Elementary and Intermediate Algebra. Be sure that you show all steps of the squaring of the binomial and multiplication along with any simplification which might be required.

Evaluate the polynomial resulting from step 1 using:P = \$200 and r = 10%, and also withP = \$5670 and r = 3.5%Colmplete problem 70 on page 311 of Elementary and Intermediate Algebra. Show all steps of the division.

2         Write a two to three page paper that is formatted in APA style and according to the Math Writing Guide. Format your math work as shown in the Instructor Guidance and be concise in your reasoning. In the body of your essay, please make sure to include:

3         Your solution to the above problems, making sure to include all mathematical work and a discussion of how and why this is applicable to your everyday life.

Plan the logic necessary to complete the problem before you begin writing.Use the underline feature with single spacing to set up the division(s), and use the “strikethrough” font to show the canceling factors. Can you think of another way this division could be approached and worked out? If yes, briefly describe the method.

4         Incorporate the following five math vocabulary words into your discussion. Use bold font to emphasize the words in your writing (Do not write definitions for the words; use them appropriately in sentences describing your math work.):

5         FOIL

6         Like terms

7         Descending order

8         Dividend

9         Divisor
