    Help with finding the domain of a function

    I'm dividing these two functions:

    f(x)=(x+2)/(x+5) and g(x)=(x+2)/(x+5)


    So,
    (x+2)/(x+5) (6x-12)/(x^2-25)

    The answer I got was (- ∞,-5)∪(5,-2)∪(2,5)∪(5,∞)

    Am I correct? I need it to be in interval notation please, thank you.

    Re: Help with finding the domain of a function

    I am not sure , but f(X) / (gx) = 1

    So I believe that the domain its all real numbers

    Now , if you are talking about this new function :

    (x+2)/(x+5) (6x-12)/(x^2-25)

    I think that is >>> (- ∞,2)∪(2,∞)

    I am not sure
