How to factor: 6x^2 -4x - 2?

OpenStudy (anonymous):

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):

have you ever done problems with factoring? How would you describe word "factorization" in your own words ?

OpenStudy (anonymous):

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. \(\Large\color{blue}{ \rm (6x+~~~)(x-~~~) }\)

OpenStudy (anonymous):

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)

OpenStudy (anonymous):

I am confused...

OpenStudy (anonymous):

Wait nevermind, I knew what I did wrong myself.

OpenStudy (solomonzelman):

Okay, nice to hear that.
