How many terms are in the expansion of (x + y)^n ( i think its n + 1 but i'm not sure if its right)
How do the expansion of (x + y)^n differ from (x - y) ^ n ? [can you explain the steps of how you got the answer]
thanks alot

The binomial theorem says:
Using this, can you explain how to answer the questions with certainty?
