Question 384066
The solution that I came up with is:


{{{(-8)/((x+2)*(x+4)*(x-4))}}}


I checked the solution out by assuming x was equal to 2 and solving both the original expression and the final expression.


They came out to the same answer leading to the conclusion that I simplified correctly.


My manual calculations are in the picture shown below:
