    is it because x^2+1 has no real solutions?

    Proving Irreducibility of Polynomials over the Integers

    If i have to show a polynomial x^2+1 is irreduceable over the integers, is it enough to show that X^2 + 1 can only be factored into (x-i)(x+i), therefore has no roots in the integers, and is subsequently irreduceable?
