The Dix Secret
editThe Dix Secret is a mathematical process named after Kevin Dix, a high school math teacher at Aberdeen Central High School[1], in Aberdeen, South Dakota. He has taught it in his Honors Algebra 2 class, when he is reviewing factoring with his students. Dix has taught for over 25 years, and is a spry and energetic man, despite being 50 as of 2020.
The process is essentially an easy way to factor something. If there is a 1 in front of an in the formula , then you can find what multiplies to receive the product c and adds to the sum of the coefficient b. This secret only works with 1 , and nothing else.
Factoring is one of the only easy things about his class, and this is just one of the things you need to do in the process of Factoring in his class.
