For this problem we solved it with k still in its place until we got to the discriminant and then we solved for k by knowing the square root of 144 was 12 and that if you wanted the discriminant to be positive k squared had to be over 144, if you wanted the discriminant to be 0 you had to have k squared equal 144, and if you wanted the discriminant to be negative k squared had to be less than 144
