It says to cross multiply, how do you even do that?????
Thanks.

Nothing to cross-multiply unless the subtraction between the two rational expressions is a mistake and should be an equality symbol.

According to what you present in your request, you have just a subtraction, and should do this:

x%5E2%2F%28x%5E2-4%29+-+%28%28x%2B1%29%2F%28x%2B2%29%29%28%28x-2%29%2F%28x-2%29%29

%28x%5E2-%28x%5E2-x-2%29%29%2F%28x%5E2-4%29

%28x%2B2%29%2F%28x%5E2-4%29-------This may be as far as should be done without changing the meaning.

Why would any solution advise one to cross-multiply? That's just silly!!!

x%5E2%2F%28x%5E2+-+4%29+-+%28x+%2B+1%29%2F%28x+%2B+2%29, simplified, is: highlight_green%281%2F%28x+-+2%29%29
