MAKE SURE IT'S IN DESCENDING ORDER FIRST!!!!
EXAMPLE: 6x3 + 9x2 + 4x - 6
NOTICE THAT THERE IS NO GCF OF ALL 4 TERMS!
Factoring by grouping says if there is no GCF of all 4 terms, look and see if there is a GCF of just 2 terms at a time.
Put ( ) around the first 2 terms and the 2nd 2 terms:
(6x3 + 9x2 ) + ( 4x - 6)
FACTOR OUT THE GCF FROM EACH SET OF TWO TERMS:
3x2 (2x - 3) + 2(2x - 3)
