We need to figure out the values of m and n. I will be posting a new animated video on my site that shows how to factor trinomials with A greater than 1. Thus if B is the negative of a square, then the constant terms of the linear factors are the two square roots of |B|. Thus we have the factorization x2 + x - 12 = (x + 4)(x - 3).
