20x^3 - 2x factoring, please help (:

OpenStudy (mertsj):

Factor out 2x first

OpenStudy (anonymous):

If you factor out the two you will get 2x(10x^2-1)

OpenStudy (anonymous):

Then you will get 2x(5x-1)(5x+1) Try FOILing it to see if it becomes 10x^2-1...

OpenStudy (anonymous):

Yah it is 2x(5x-1)(5x+1)

OpenStudy (anonymous):

So do you understand it well enough?
