Hello from MrBillDoesMath!
  
Answer:
x^5 - 5 x^4 y + 10 x^3 y^2 - 10 x^2 y^3 + 5 x y^4 - y^5
Discussion:
Pascal's triangle looks like this (up to 6 rows)
     1  
    1 1  
   1 2 1  
  1 3 3 1  
 1 4 6 4 1  
1  5 10 10 5 1
The last row contains the constant multipliers in the equation. The terms in the expansion alternate in sign.
Thank you,
