You should get:
(x+5)/(x+4)
[(x+6)(x+2) / (x+6)(x-2)] / [(x+4)(x+2) / (x+5)(x-2)]
Of course, the solution is valid for:
x NOT equal to -6, 2, -5, -4, -2 as any of these values would zero out your denominators.

Don't plug it into your calculator, factor the quadratic expressions and cancel like terms!
Your expression factors as:
(x+6)(x+2)/((x+6)(x-2))
-------------------------------
(x+4)(x+2)/((x+5)(x-2))
= (x+5)/(x+4)

I get 1/[(x-2)^2(x+4)(x+5)]

My calculator yelled at me about not using variables so no I did not get that.

Ask this to prof Steven Hawking, he is very good at mathematics.
