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.
You rock, Thank you so much!!! I have end of the year exams tomarrow and my teacher sucks at teaching this. he knows the material, but can't teach it well so Thank you!!! I finally Get it!!
hello sir/mam, i would like to thank you for being helpfull i know that you shuold be payed for this but it only show that you care,i praised you for this and recommend to keep it up you just dont this really helpfull for those who having hard time to understand the lesson oneway ot he other your fruit of labor will come for sure..and i'm one of them thanks again and pls dont get tired of this god bless
It´s a lot easier to teach the grouping or triple play method....none of this guessing....This is the way they taught us in school as well...take -5 and multiply it by 4....then split the 2nd term up and then factor...a lot easier:) Alex

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?

Just want to say thx. Ive looked at a lot of your videos and they have really helped. I just wish my math teacher taught it that well.

how did u get the -4
pooja2092 3 years ago
At the beginning, the -4 was found because I factored a negative one first.

this is bs i still dont understand

Why do it by guessing? Do it by more formal means, like grouping or completing the square. Look at my other videos.

just (a)(c)=-30 and find the factor of it who's sum is -7 which is -10 and 3!then factor 2x(squared)-10x+3x-15 by grouping!!!
