MAT 221 MAT221 Week 1 Discussion Evaluating Algebraic Expressions (Ashford)
MAT 221 Week 1 Discussion (New)
- Evaluating Algebraic Expressions. Read the following instructions in order to complete this discussion, and review the example of how to complete the math required for this assignment:
- Write your birth date or the birth date of someone in your family as mm/dd/yy. (Example: March 13, 1981 is written 3/13/81, and November 7, 1967 is written 11/7/67).
Now let a = the one- or two-digit month number,
b = the negative of the one- or two-digit day number, and
c = the two-digit year number.
(Our example: a = 3, b = -13, and c = 81 or a = 11, b = -7, and c = 67)
- Use the following algebraic expressions for parts c-d of the discussion:
b–c 2b – a
c. Evaluate the three given expressions using the a, b, and c from your birth date. Make sure that b isnegative when you plug in the values.
- After you have your math worked out on scratch paper, post your results as well as a description of the steps you took to evaluate the expressions.
Did you notice anything interesting about the results of a3 – b3 and (a – b)(a2 + ab + b2)? Was this coincidence or do you think there is a reason for this?
- Incorporate the following five math vocabulary words at least once 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.):
Lowest terms Divisor
Your initial post should be 150-250 words in length. Respond to at least two of your classmates’ posts by Day 7 in at least a paragraph. Do you agree with how your classmates used the vocabulary? Did the student handle the negatives in the formulas accurately?
