Factoring Polynomials 11/5/2014 Factoring Objective: factor a quadratic expression where the a term does not equal one. Students apply basic factoring techniques to second-and simple third-degree polynomials. These techniques include finding a common factor for all terms in a polynomial, recognizing the difference of two squares, and recognizing perfect squares of binomials.

Notes • Steps for Factoring a Quadratic Equation 1) Factor out the GCF (if possible) 2) Set up the Magic X. • ac goes on top, and b goes on bottom • Find the pair that multiplies to equal the top, and adds up to equal the bottom. 3) Set up the Magic T. • Put ax on the top two, and the pair we found for the bottom two. • Treat each side as a fraction and reduce if possible 4) You now have your factors.
