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: 1. 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). o Now let a = the one- or two-digit month number, o b = the negative of the one- or two-digit day number, and o c = the two-digit year number. (Our example: a = 3, b = -13, and c = 81 or a = 11, b = -7, and c = 67) 2. Use the following algebraic expressions for parts 3-5 of the discussion: a 3 – b 3 (a - b)(a 2 + ab + b 2 (b – c) (2b – a) 1. Evaluate the three given expressions using the, b, and c from your birth date. Make sure that b is negative when you plug in the values ) . 2. 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 a 3 – b 3 and (a - b)(a 2 + ab + b 2 )? Was this coincidence or do you think there is a reason for this? 3.
