How to Factor a Trinomial by Guessing 15x^2 - 22x - 48

TL;DR

Factoring challenging polynomial expressions through trial and error can be frustrating but rewarding.

Transcript

hi in this problem we're going to try to factor this solution so this one does not look simple at all so i'm noticing that there's no common factor for example i can pull out a 3 here from the 15 and pull out a 3 here from the 48 but you really can't pull anything out from the 22 other than a 2 or an 11 so no common factors we can deal with also wh...
