MI3 HelP Fall 2016
Final HW Help:
HINT FOR 118, A.
18b ( b^2 - 216 ) = 0, if you do not come across this step, then you will find the wrong b, then the wrong a. Once you get to this step equation, Use Zero Product Property to find b. Then you can find, a. Then write your equation (check it). This problem can also be done using different kind of substitution, however, you still have to come across the "216", that step would be b^3 = 216. Which can lead you to find; b, then, a. 118. B. see picture below. Show steps on your work. |
117 Help see picture above.
In problem b. Given: 7g(x), it means for you to multiply 7 times g(x) which is x - 3. So multiply 7(x - 3), and the result of that is what 7g(x) = __________ . Number 116 re: Log problems, scroll down to Log section below. |

PROBLEM SAMPLE WITH THE MATH PRACTICESSample of the Math Practices (MP.'s) "at work."
Problem from the MI3 textbook from Ch. 2. p. 68, part a. Shows and explains why each of the Math Practices noticed are needed to find x given a pair of similar triangles. EFFECTIVE WEEK OF NOVEMBER 14, ANY MAKE UP* ASSIGNMENT CAN BE TURNED IN SHOWING AND EXPLAINING USING FULL SENTENCES AND JUSTIFICATIONS PER HW PROBLEM. Missing HW-Make Ups. GIVE and EXPLAIN THE USE OF EACH OF THE MATH PRACTICES (plural, per problem, 2 or 3 MP.'s). Full sentences to specific terms, concepts, or skills demanded of the assignment are expected, while making references to the MP.'s FOLLOWED BY A LEARNING LOG SUMMARY FOR THE WHOLE ASSIGNMENT OF THE MAIN OBJECTIVES & CONCEPTS LEARNED, NEEDED, REVIEWED, OR PRACTICED OF THE ASSIGNMENT. *A make up assignment is an assignment missed that has been graded by teacher, and it has been handed back to students. Hence, its integrity is at jeopardy. Therefore, you will need to redo the assignment, along side justified MP statements, per problem and a summary of it, to make up for that assignment. At the same time you will expand your domain of becoming more mathematically proficient as a mathematician. |

Go over the factoring selected problems first, if you need a quick refresher on factoring.
As an MI3 student and future Calculus student, you are responsible for knowing how to factor:
1. Greatest Common Factors of Polynomials
2. Difference of Squares
3. Trinomials
4. by Grouping
(aforementioned are included in the files above).
5. Difference of Cubes (google please)
6. Sum of Cubes (google)
