\left(x^{2}+4\right)\left(x^{2}-3\right)
Find one factor of the form x^{k}+m, where x^{k} divides the monomial with the highest power x^{4} and m divides the constant factor -12. One such factor is x^{2}+4. Factor the polynomial by dividing it by this factor. The following polynomials are not factored since they do not have any rational roots: x^{2}-3,x^{2}+4.
