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.

3. 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.
