1. BecomeMyFan=D

$((3x+6) \div (x ^{2}+3x+2)) * ((x+1) \div (2x+8) )$

2. BecomeMyFan=D

i really bad at this stuff i need to simplyfy this

3. mstud

This becomes, if I interpreted your expression correctly:

4. lokisan

Okay...

5. lokisan

$\frac{3x+6}{x^2+3x+2}. \frac{x+1}{2x+8}=\frac{3(x+2)}{(x+1)(x+2)}. \frac{x+1}{2(x+4)}$$=\frac{3}{2(x+4)}$

6. lokisan

It's just about factorizing and cancelling common factors.

7. mstud

Ouch, my answer was deleted by the browser or the web page. but now you got the answer anyway ;-)

8. lokisan

Sorry, mstud, I thought you weren't interested in it anymore. This browser destroys hard work all the time - I feel your pain.

9. mstud

Well, with the old version destruction was even worse, when the whole answer was written, it didn't always save automatically, and I either had to copy the whole answer I had written go back , open the question once more and then paste the answer in again or write it all over again. It doesn't matter that you answered instead, the most important is that "BecomeMyFan=D" got an answer to the question:)

10. lokisan

Lol, I know! That's the kind of crap I had to do too!

11. mstud

Now it's usually enough to refresh the browser,but not always, though

12. lokisan

Yes. I hate how the window keeps jumping while typing, too. I hope someone mentioned that in the customer feedback thing today.

THANK YOU GUYS!I can see that my problem was wih factorising of the quadratic equation part, thank you!

and yes, this site has LOTS of bugs. I can see that the programmers are beginners.
