(x)(x+1)(x+2)-(x-1)(x)((x+1)

The answer is 3xsquared + 3x. How??

I know theres prob a real easy way to do this so excuse me for my stupidity when it comes to math🙂

Got it now thankss.. if it wasnt for that shortcut does that mean that in the first expression you would have to mutiply x by both (x+1) and (x-2) or can you multiple
x(x+1) and use that answer which is x2 + x and multiply that by (x-2). Is that the same thing?
