Tell me, after doing the formula and thing, we end up with:
(6x^2+2x)(-6x-2), correct?
OpenStudy (anonymous):
I have no idea what to do next. >_<
OpenStudy (solomonzelman):
You are incorrect.
OpenStudy (anonymous):
Oh. Tell me what I mess up with?
OpenStudy (solomonzelman):

How would you describe word "factorization" in your own words ?

Reducing an expression to its lowest term?
OpenStudy (anonymous):
I've done factoring when c is greater than b; cause I can use the big x. But I can't do it for this one. =/
OpenStudy (solomonzelman):
I do it just by thinking how to expand it. I am going to give you a hint, and you will fill in blanks.

I can guess and check, but that would awfully take a long time.
OpenStudy (solomonzelman):
your guesses can only be factors of -2 (because it is the last term)

Wait nevermind, I knew what I did wrong myself.
OpenStudy (solomonzelman):
Okay, nice to hear that.
