Factor This - Yeah, math, whatever.

Factor the polynomial . x2 - 49 = (x2 is the square of x, 49 is the square of 7) (x)2 - (7)2 = (x - 7)(x + 7). You may have to factor out a GCF from the two terms before you recognize the DOS: (note - a big principle of factoring is that we always factor out a GCF first if it can be done). Example 7: Factor the polynomial ................
