FACTORING – Difference of Squares Factoring difference of squares is probably the easiest factoring you will encounter. The wording difference of squares is just that, it is a two term expression, both of which are perfect squares, with a negative sign between them. Format : Let’s review multiplication of binomials. If we multiplied using FOIL or the array, you would notice that the MIDDLE term would = 0. The factors of 4 that add up to zero are +2 and (– 2).
