Factoring General Polynomials (Grouping Number GN)

WHAT TO DO:	HOW TO DO IT:
Example: 6x² + 23x + 20	6x² + 23x + 20
Multiply 6Â· 20:	GN 6Â·20 = 120
Find pairs of integer factors (largest first)
Sign before last term is + so find pair with the SUM of 23	15 + 8 = 23
Both have same sign as middle number + 23	+15, + 8
Rewrite polynomial 6x² + 23x + 20 with 4 terms having correct signs:	6x² + 15x + 8x + 20
Group terms 2 by 2	6x² + 15x + 8x + 20
Factor common term from each group:	3x(2x + 5) + 4(2x + 5)
Note that (2x + 5) is now common factor and factor it out to get:	(3x + 4)(2x + 5)
Multiply by FOIL to check: Check: Always Check:
