Need help solving 9x^3 - 42x^2 - 24x  TOPIC_SOLVED

9x^3 - 42x^2 - 24x

All I have so far is:

3x(3x^2 - 14x + 8)

Can someone please help me understand how this works?

Thank you. I'd already reviewed the page before coming here.

What I really need is a solution to the problem I posted.

I don't know if I solved it correctly.

I did post it in the first reply. I needed to know if I was right or wrong and why. You're of no help.

I posted on yahoo answers and got a detailed explanation within 20 minutes.

Getting the run around was not helpful and I will not recommend this site to others in my math class.
