Normally, when we do a factoring problem, we are trying to find two numbers that multiply to 12 and add to 8. Those two numbers are the solution to the quadratic, but it takes students a lot of time to solve for them, as they’re often using a "guessandcheck" approach.
Instead of starting by factoring the product, 12, Loh "starts with the sum", 8. If the two numbers we’re looking for, added together, equal 8, then they must be equidistant from their average. So the numbers can be represented as 4–u and 4+u. When you multiply, the middle terms cancel out and you come up with the equation 16–u2 = 12. When solving for u, you’ll see that positive and negative 2 each work, and when you substitute those integers back into the equations 4–u and 4+u, you get two solutions, 2 and 6, which solve the original polynomial equation. It’s quicker than the classic foiling method used in the quadratic formula and there’s no guessing required. Dr. Loh believes students can learn this method more intuitively, partly because there’s not a special, separate formula required. If students can remember some simple generalizations about roots, they can decide where to go next.
It’s still complicated, but it’s less complicated, especially if Dr. Loh is right that this will smooth students’s understanding of how quadratic equations work and how they fit into math. Understanding them is key to the beginning ideas of precalculus, for example. 
Outside of classroomready examples, the quadratic method isn't simple. Real examples and applications are messy, with ugly roots made of decimals or irrational numbers. As a student, it's hard to know you've found the right answer. Dr. Loh’s new method is for real life, but he hopes it will also help students feel they understand the quadratic formula better at the same time. REF :: https://arxiv.org/abs/1910.06709
