Question

2.) Two students are working on a simplification problem. Their work is shown below. Is either of

them correct? If so, who? And what did the other do wrong? If not, show how to get the correct
answer and explain what each did wrong?

Answer 1

Both Jeff and Lori are wrong.

Explanation:

`3 - ((4 * 3)^(2) )/(2) + (1 * 6)`

`3 - (12^(2))/(2) + 6`

`3 - (144)/(2) + 6`

`3 - 72 + 6`

`- 72 + 9`

`- 63`

-63 is the final answer
