Rules of Factoring

100

What is the first thing you need to find out when factoring?

Is there a GCF to pull out

200

What is the second thing?

Does A = 1

300

What if A=1

Multiplying number is your C and addition number is your B

400

What if A doesn't equal 1

Multiplying number is A*C and addition number is B

500

What do you call a trinomial that can't be factored?

PRIME
