%28%28x%5E2-16%29%2F%28x%5E2%2B5x%2B6%29%29%2F%28%28x%5E2%2B5x%2B4%29%2F%28x%5E2-2x-8%29%29...replace 16 with 4%5E2, then 5x with 2x%2B3x%7D%7D%2C+then+%7B%7B%7B5x with x%2B4x%7D%7D%2C+then+%0D%0A%7B%7B%7B-2x with








%28%28x-4%29%28x-4%29%29%2F%28%28x%2B3%29%28x%2B1%29%29%29%29

since denominator cannot be equal to zero, restrictions on the variables exist and if

%28x%2B3%29=0........x=-3 and
%28x%2B1%29=0........x=-1...there will be no solution
so, variable x cannot be equal neither -3 nor -1
