1. ## Math help!!

Anyone know how to do this?
I can't see to get the answer right..
$\frac{{\frac{{{{x}}^{{2}}+{3}{x}-{4}}}{{{{x}}^{{2}}-{7}{x}+{12}}}}}{{\frac{{{x}+{4}}}{{{x}-{3}}}}}$

2. Hmm i cant see whats goin on

3. It's all dividing by it's self..
Can you not see the picture? lol

4. do you have the link to the picture because its tiny

5. (you need an account to see links)

doubt you'll be able to see it as it's on my homework. lol

6. (x-1)
----- <division sign
(x-4)

7. I understand that.. i dont' understand how to do the whole entire problem..

8. Umm okay

reverse foil the top two lines
x^2+3x-4 become (x+4)(x-1)
x^2-7x+12 becomes (x-3)(x-4)

(x+4)(x-1)
----------
(x-3)(x-4)
-------------
x+4
--------------
x-3

now cross out the x-3 and x+4
and you are left with
(x-1)
----- <division sign
(x-4
