Factoring a ~1 BOX METHOD Factor 2x 2 + 9x + 4 Because there is a number in front of the x 2 term, you should first look for a there is no GCF, we must factor this a different way. • Aft J:. . Since METHOD 1: The Box Method Jx • Next, multiply the {)., term and the (!. term. You must find numbers that multiply to this number (a· c) that add to the le, number (b). Put these two numbers in the to.e. right and bottom left squares. Don't forget the )( ! Now take the out of each column and row and write it outside the box. • Rewrite these terms as • M(dd (::;\C f bt ·(l.
