Answer:
Step-by-step explanation:
|3x+12|
one is as it is one is the negative value of it
3x + 12 - (3x + 12)
- 3x - 12
That is because both negative and positive values put in am absolute value become positive.
Given:
The expression is:

To find:
The difference.
Solution:
We have,

It can be rewritten as:


Taking LCM, we get




Therefore, the value of the difference is
.
Looking at a number in different ways can help understand it’s application better. For example, giving an answer with radicals(square roots) is precise, but it’s not practical because you really don’t know what that number means.
I assume it is:
2x/(-5x+x^2), then you can simplify the x, but only if it is not zero:
2/(x-5), for x different to zero.
