add simplify if possible
2y/y^2-9 + y/7-3
:
Assume you mean
%282y%29%2F%28%28y%5E2-9%29%29+%2B+y%2F%28%28y-3%29%29
:
We can factor the 1st denominator as the "difference of squares"
%282y%29%2F%28%28y-3%29%28y%2B3%29%29+%2B+y%2F%28%28y-3%29%29
Combine as a single fraction
%282y%2By%28y%2B3%29%29%2F%28%28y-3%29%28y%2B3%29%29 = %282y%2By%5E2%2B3y%29%2F%28%28y-3%29%28y%2B3%29%29 = %28y%5E2%2B5y%29%2F%28%28y-3%29%28y%2B3%29%29 = %28y%28y%2B5%29%29%2F%28%28y-3%29%28y%2B3%29%29
