OpenStudy (anonymous):

Do you see the GCF?

OpenStudy (anonymous):

4x? Right?

OpenStudy (akshay_budhkar):

yes right. Take that common now

OpenStudy (anonymous):

So that makes it... 4x(x^2-x-2)? Or no?

OpenStudy (akshay_budhkar):

Yes you are right.. Go ahead factorize the quadratic now

OpenStudy (akshay_budhkar):

Can you do that?

OpenStudy (anonymous):

I think? I'm not entirely sure..

OpenStudy (anonymous):

4X^3 - 4X^2 - 8X = 4x ( X^2 -X - 2 ) = 4X ( X-2 ) ( X+ 1 )
