Question 8588: Are there always two answers when solving for an absolute value? Do you have to put the positive and negative or no? Here is my problem and here is my answer:
7-4(3-6)2 (that 2 is squared not a regular 2)
---------
|3 -12|
so I got
3(-3)squared 3(9) 27
----- ---- -- = 3
| -9 | 9 9
So is that answer right or is it {3, -3}?

I'm not sure, is this what you mean for the problem?

+%287-4%283-6%29%5E2%29%2F%28abs%283-12%29+%29

If this is it, then you must do the parentheses first: (3-6) = -3 and within the absolute value, (3-12) = -9.

+%287-4%28-3%29%5E2%29%2F%28abs%28-9%29+%29

Next, do %28-3%29%5E2=9 and abs%28-9%29+=+9

+%287-4%2A9%29%2F9+

Next, multiply 4*9=36

+%287-36%29%2F9
-29%2F9

Does that look right?
