ax^2 + bx + c

Example:

x^2 - 5x - 6

you have to times a and c, but since a is 1 and c is -6 it will be -6

factor (ac) l sum b

factor (-6) l sum -5

now factors that can go into -6 have to add up to -5

in this case 1 + (-6) = -5

so you will put it into parentheses.

(x + 1) (x - 6)

that would be the answer.

then if you foil it.

It would come back out as 

x^2 - 5x - 6
