When you have a number divided by something divided by something divided by something, how do you do it? I have to simplify

(x+3)(x-1)
--------------
(x+2)(x-2)
-------------
(x+6)(x+1)
-------------
(x+2)


Please help!
#2
(x2+2x-3)/(x2-4)
---------------------
(x2+7x+6)/(x+2)

i think ....

[x2 being x squared]

(x+6)(x+1)=x^2+7x+6 if that helps. I'm only in Algebra 2.

In a situation like this, multiply by the reciprocal of the divisor:

(x+3)(x-1) .............. (x+2)
-------------- .....X......--------------
(x+2)(x-2) .............. (x+6)(x+1)

and solve in normal mathematical fashion with normal multiplication and division rules.

I won't take the answer any farther, haha, I don't mind helping but I'm a teacher and I can never bring myself to give someone an answer.

BTW, ignore the dots, I just added them in there so the formula would space correctly

(x+3)(x-1) (x+6)(x+1)
-------------- / --------------
(x+2)(x-2) (x+2)

and then you just change it to a multiplication question.

(x+3)(x-1) (x+2)
-------------- x --------------
(x+2)(x-2) (x+6)(x+1)

and solve. I think that's how...

or you can bring the denominator up and make it to the power -1, but im not sure that will be much help. Just times by the reciproca like someone said up there.

That is right you just need to nustiply top by top and bottom by bottom now.

Thank you reciprocal guy!! I was supposed to learn that a while ago, but somehow I skipped it or something
