  • This method consumes too much time for guessing and checking the terms of the 2 binomials in x, due to high number of permutations. There is a new method, called Diagonal Sum Method, that directly gives the 2 roots WITHOUT factoring. It reduces the number of permutations in half, and is applicable whenever the equation can be factored. See book title:" New Methods for solving quadratic equations and inequalities" (Trafford 2009).

  • You are right, there are many ways to factor, and just recently there has been an explosion of the "X" method. The most important thing is, can you learn and demonstrate the concept? If you can do it with any method, you are one step ahead of everyone.

  • Very inefficient method. strategic guess and check and decomposition methods are significantly better, and fast!

  • I agree, but there will always be a student who will want to guess! My teacher used to guess!

  • How would u complete this problem without guessing?

  • Check with my other videos. I do it without guessing.

  • At the beginning, the -4 was found because I factored a negative one first.
