Hello to all the community , I'm new to this forum

I apologize if Iwrite something that is not understood , I will be very concrete.

The exercise is as follows.

calculate and indicate that values of X is defined the ratio.

My resolution

First thing I did was multiply polynomials crossed (x-3 ) * (8x + 16x^2)

and ( 4x ) * ( x^2 - 9 )

and then re-divide the remaining fraction of polynomials but I realized that Ido not get anything.

Then I can not understand the part where it says

Please if anyone can help I would appreciate it !"for values of X is defined the ratio"

Best of luck to everyone!
