Fellow math people, I am stuck! My class is working on factoring ax2 + bx + c. No problems when a=1, but they are really struggling when it's not. So far I've just been having them make lists of factors for a and c then try a few of the combinations. From there they are supposed to see if b needs to be more or less and adjust which factors they used and in which order to try to find the correct factorization. They are getting frustrated that there is no "trick" to this and that sometimes there are 32 possible factorizations! It seems to me that the perfect square discriminant rule only applies when a=1 so now they have to try all the possibilities before they can say something is not factorable. Am I missing something? I have reread the section over and over and can't find anything new to tell them! Thanks!!!
