Does not factor.

Work Step by Step

Since the coefficient of the squared term is one, we know that the expression must factor to: $$ (n\pm a)(n\pm b)$$ Here, we see that a and b must multiply to get $9$ and add to get $-3$. Thus, we find that the solution is non-existent. This expression does not factor easily.
