Compact l x-2 l - l x-3 l
I need fast
Thank you !
P/s : l x l is absolute value

You can't solve this without a specific value of x.

Step-by-step explanation:

Well, all that the absolute value sign means, is that you work in them like parenthesis, but when you "open them up" no matter what, the result will be positive.

So, | x - 2 | - | x - 3 | is just a showing you that you are going to have a positive answer for x - 2, and you are going to have a positive answer for x - 3.

Now, since we don't have a specific value for x, just to simplify this even more, lets just quickly substitute x = 1, just for a reference, so:

| 1 - 2 | - | 1 - 3 | = | -1 | - | -2 |

                         = 1 - 2

                         = -1

Ok, so we got that, now we can go back to the original problem. Since we really don't have a specific value for x, we can't really simplify this any further. Maybe if you had a specific value or placeholder for x, then you would be able to solve this.
