1. Factoring GCF – Greatest Common Factor Difference of 2 Squares Factoring by Grouping Factoring Trinomials

2. Factoring by Grouping Try to group terms that will favorably produce a common factor after using GCF: Example; 2x 2 + 6x – 4x – 12 Group and factor out GCF; 2x(x + 3) – 4(x + 3) Then factor out (x + 3) (x + 3)(2x – 4)

3. Example 2x 22x 3 – 12x 2 + 18 – 3x (rearrange terms to anticipate grouping) 22 2x 3 – 12x 2 – 3x + 18 (factor out GCF for each group) (factor out negative 3 for 2 nd group) 22x 2 (x – 6) – 3(x – 6) Solution; (2x 2 – 3)(x – 6)
