If anyone has their OG 12 book handy, I'd like to know if there is a shortcut to solving any problem related to #148 in the Problem Solving section (page 173).
I get about half-way through the simplification/factoring of the initial formula, but then the "official answer" explains further steps to take that I simply/honestly never would have thought of - especially in a 2-minute time allotment.
In other words, how can I tackle such questions that give you three variables,...then tack on a "x < y" expression....and then list integers as the answers?
Many thanks....
