The best you can do is simplify.
12x (x+3) 12x 4x
_________ = _____ = ____
15 (x+3) 15 5
Faxtor out (x+3), reduce to lowest terms (4x/5)

Be sure to ask your teacher what all this 4x/5 answer stuff is all about.
Look at 3x + 9.
See how both terms, 3x and 9, are divisible by 3?
Look at x^2 + 3x
See how both terms, x^2 and 3x are divisible by x?
What's leftover when you factor out the 3 and the x? The same thing! Good luck finishing this up and getting the answer the rest of the helpers got for you!

Its simple....
12/5 will be the number = 2.4
so:
2.4 (x^2 + 3x)
___________
(3x+9)
CAN BE FURTHER SIMPLIFIED by taking 3 as common factor
2.4 (x^2 + 3x)
___________ =
3 (x+3)
0.8 (x^2 + 3x)
_____________
(x+3)
take X as common factor in the numerator
0.8x (x + 3)
_____________
(x+3)
CROSS OUT THE (X+3)
So the final answer is
0.8 X
Hope you got the point :)

Well, I'm not sure right now, but I asked a question about where I could find math help! I got this site!
Scroll DOWN to a table of contents (Ignore the "ad" links to the left). There's quite a bit of algebra stuff (see part 2 in the table of contents).

12x(x+3)/15(x+3)=12/15=4/5

= you can make it simple :
= 12x(x+3) / 5 [ 3 ( x+3 ) ]
then you can omit x+3 from the top and the bottem :D
3(4x)/5*3 = 4x/5 !
that`s it !

I am afraid your text and figures donot agree.

multiply the numerators and then the denominators. next, just simplify your answer.
