Factoring quadratics using the AC method 

I’ve got to say, I really appreciate this video, I really hope schools can teach students easier method on how to solve problems in math. Thank you for your hard work on this video

Thanks so much!! This was confusing to me, but after seeing this, I understand it a lot better!

They never showed us that in school it just makes it so much easier

I the quadratic formula seems less complicated. Maybe because I learned to start with the general and then apply it.

We used to call it the trial and error method

(3x-15)(3x-4) but 3(x-5)(3x-4) so it is (x-5)(3x-4) from components getting rid of common factor.
