I'm assuming you want to factor this.



x%5E3%2By%5E3 Start with the given expression.


%28x%2By%29%28%28x%29%5E2-%28x%29%28y%29%2B%28y%29%5E2%29 Factor by using the sum of cubes formula. Remember the sum of cubes formula is A%5E3%2BB%5E3=%28A%2BB%29%28A%5E2-AB%2BB%5E2%29


%28x%2By%29%28x%5E2-xy%2By%5E2%29 Multiply

-----------------------------------
Answer:

So x%5E3%2By%5E3 factors to %28x%2By%29%28x%5E2-xy%2By%5E2%29.

In other words, x%5E3%2By%5E3=%28x%2By%29%28x%5E2-xy%2By%5E2%29
