| 1st step in factoring that you cannot forget!!! | LOOK FOR GCF!!! (this applies to DOS or Crummy Crummy SOPS as well) 1: negative sign 2: largest # 3: variable ALSO: after u find GCF, make sure you can't GCF it anymore! if you still can, that means you can find a larger number/variable!!! |
| things to remember (1): | 1: make sure if you take out a GCF, make sure to add that # in the beginning of your final answer 2: make sure to use the correct variable in your answer and not always 'x' 3: use correct signs (- or +) |
| DOS: | Ex: x² - 25 1: 2 terms 2: HAS TO BE subtraction 3: both perfect squares D: double ( ) O: opposite signs S: square root BOTH terms |
| Crummy Crummy SOPS: | Crummy: cube root 1st term Crummy: cube root 2nd term S: square 1st term O: opposite term P: product of first parenthesis S: square 2nd term *can be subtraction or addition!!! |
| If a polynomial has a GCF, then it is _____ __________. | not prime ex: 3m^2 - 3 has a GCF of 3, thus, this polynomial is NOT prime |
| perfect square trinomials: | trinomial w/ a perfect square for 'a' & perfect square for 'c', you MIGHT have a perfect square trinomial. try the square roots of 'a' and 'c' as the first set of parentheses and if it doesn't work then go back to the list of factors (womp womp) |
| FOIL stand for: | First Outside Inside Last |
| other things to remember (2): | -make sure to write the GCF in every step of the problem so you don't forget to write it in the final answer -for choose that apply problems, solve all problems; do not just assume something about it |
