factor completely. remember to look first for a common factor. if a polynomial is prime state this. x^2+2xy+y^29

Try factorizing the first three terms using the identity:
(a+b)² = a² + 2ab + b²
The resulting difference of two squares can be factorized using the identity:
(a²b²) = a²  b²
Post your answer for a check if you are not sure.
