Unformatted text preview: Week 1 math 222 introduction Since this course is the second half of the Algebra material covered in MAT221, a brief review of its last topic is also included in the introductory post. Factoring is the key to everything we do in Week One of MAT222, so it is important that your factoring skills are sharp and ready to go! Please, find the two problems assigned to you in the table below. If the third letter of your last name is On pages 345-6, do the following problems A or N 70 and 62 B or O 90 and 56 C or P 74 and 60 D or Q 88 and 58 E or R 78 and 52 F or S 86 and 76 G or T 80 and 106 H or U 72 and 104 I or V 98 and 102 J or W 68 and 100 K or X 82 and 96 L or Y 66 and 54 M or Z 92 and 64 PROBLEMS ARE : 98. 3h^2 t + 6ht +3t 102. -3 + 2y + 21y^2 Factor the polynomials using whatever strategy seems appropriate. Referring back to the processes covered in Chapter Five of Elementary and Intermediate Algebra , state which factoring methods you will use and then demonstrate the methods on your problems, explaining the process as you go. Discuss any challenges those particular polynomials posed for the factoring. Week 1 math 222 disc 1 Domains of Rational Expressions In this discussion, you are assigned two rational expressions with which you will work. Remember to factor all polynomials completely. Read the following instructions in order to complete this discussion: Rational expression problems are bellow First Rational Expression Second Rational Expression 64a^2 – 9/ 16 m^2 + 2m – 15/ 3m^2 - m Explain in your own words what the meaning of domain is. Also, explain why a denominator cannot be zero. Find the domain for each of your two rational expressions. Write the domain of each rational expression in set notation (as demonstrated in the example). Do both of your rational expressions have excluded values in their domains? If yes, explain why they are to be excluded from the domains. If no, explain why no exclusions are necessary....
