Steps :
(1) Factor out the GCF of all the terms .
(2) If the polynomial has :
- two terms , check to see if it is a difference of cubes , a sum of cubes ,
or a difference of cubes;
- three terms , guess (. . . and check with F O I L) or use grouping ;
- four or more terms, try grouping.
(3) Be persistent and careful!
