%282x-y%5E2%29%2F%28x-y%29 Start with the given expression.


%282%2810%29-%28-5%29%5E2%29%2F%2810-%28-5%29%29 Plug in x=10 and y=-5


%282%2810%29-%28-5%29%5E2%29%2F%2810%2B5%29 Rewrite 10-%28-5%29 as 10%2B5


%282%2810%29-25%29%2F%2810%2B5%29 Square -5 to get 25


%2820-25%29%2F%2810%2B5%29 Multiply


%28-5%29%2F%2815%29 Combine like terms.


-1%2F3 Reduce


So %282x-y%5E2%29%2F%28x-y%29=-1%2F3 when x=10 and y=-5


So either you entered the problem in wrong or there's a typo somewhere in your book. Is there something missing? Repost with the clarifications.
