Well I presume they are explaining it like you would destribute the negative in front of the first part of the problem through it.
the hint part
I have no knowledge of how to do this.
...I did this last year...DARN MY DUMPING OF KNOWLEDGE!
@Mertsj I hate to drag you here...
If I am not mistaken I think you would cancel the 2x out but dont take my word for it

The choices are: 2/3 3/2 x - 4 x + 4 I don't understand what he wrote.-.
Work the last part out
I guess
- 2/3 ? x - 4 ?
I really don't understand ;(
What part don't you understand? The part where I factored the numerator or the factorization of the denominator?
I don't understand the whole thing.
Take the denominator which is 3x-12 and factor out a 3 and post what you get.
x - 4?
NO!! When you write the factors of something, they must multiply back to the original expression.
3x-12=3(x-4)
Now take 8-2x and factor out -2 and post the result.
-2(x - 4) ?
Now write the entire fraction with the numerator and denominator in their proper places and factored.
-2(x - 4) -------- ? 3(x - 4)
Do the numerator and denominator have any factor that is the same?
x - 4 ?
So what could you cancel?
Cancel out x - 4?
What question are you trying to answer?
Which factor can you cancel from the numerator and denominator to simplify?
And the answer is?????
x - 4?
Very good.
