\[\frac{ 8 - 2x }{ 3x -12 }\]

2
- ?
3

If you cancel A out.

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

|dw:1373161125061:dw|

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 ;(

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) ?

-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.
