Since you have a sum of two squares (), this means that you cannot factor over the rational numbers (if it were a difference of squares, it would be a different story).

However, if you want to factor over the complex numbers, then . However, chances are that you aren't studying complex numbers.

If this is the case, then can't be factored and it is prime.
