Monday 9/28 Homework for House 4 (Classes 449 and 451)

In the picture below are the two answers that were given for the expression we simplified in class today.



For homework tonight (Monday 9/28), look at the two approaches and decide which simplified answer you believe is correct.  Then answer the following questions in the Homework section of your notebook.

1) Which answer do you think is correct?  Why?

2) Which mistake was made in the answer that wasn't correct?
Bonus: How could you correct the mistake?
