    suppose ur pair is a+b, then if ab is even, u can evaluate k=ab/2

    and then multiply the 2 terms in each of the pairs and divide them by 2 to get k

    so when u factor this expression out...u first multiply the c oefficient of the first term with the third

    when u factor this expression out...u first multiply the c oefficient of the first term with the third..and then u break the middle term into a sum, for eg if its x^2 + 5x + 6 the product is 1x6=6 so we break 5x into 2x + 3x, see 2.3 is 6 the same as 1.6 , dont we do that?
