http://www.purplemath.com/modules/factquad.htm Read this it goes into it in depth. I'll explain the cliffnotes right now. But I really suggest looking at the link. Factoring is used often and is important

anonymous · Answer

you want to look at the last term. It is usually a constant, in this case look at the coefficient. By experience I know right away that when I see the pattern 1st "-" 2nd "+" 3rd
that the factor will be (x -  )(x -  ). 

Now the last term is 24 so we want to think about the factors of 24 that when you add them will equal -10. Since I already know the only way to do this is -6 times -4. added equals -10

(x - 4y)(x - 6y)

Basically the factors of the last term add to the middle term. Those numbers go into the factored form
