###### Example7.1.13

Factor $$4m^2n-3xy\text{.}$$

There are no common factors in those two terms (unless you want to count $$1$$ or $$-1\text{,}$$ but we do not count these for the purposes of identifying a greatest common factor). In this situation we can say the polynomial is prime or irreducible, and leave it as it is.
