xy%28x%5E2%2B3xy%2B9%29 Start with the given expression


%28xy%29%28x%5E2%29%2B%28xy%29%283xy%29%2B%28xy%29%289%29 Distribute xy among the terms in the parenthesis


x%5E3y%2B%28xy%29%283xy%29%2B%28xy%29%289%29 Multiply xy and x%5E2 to get x%5E3y

x%5E3y%2B3x%5E2y%5E2%2B%28xy%29%289%29 Multiply xy and 3xy to get 3x%5E2y%5E2

x%5E3y%2B3x%5E2y%5E2%2B9xy Multiply xy and 9 to get 9xy


-------------
Answer:
So xy%28x%5E2%2B3xy%2B9%29 distributes to x%5E3y%2B3x%5E2y%5E2%2B9xy

In other words, xy%28x%5E2%2B3xy%2B9%29=x%5E3y%2B3x%5E2y%5E2%2B9xy
