Hey guys, I got this problem on my math sheet and I have no idea if I did it right because it's the first time I see something with a division and two multiplications.

Do I have to flip the last two? Or just the middle one? I am now confused (Thinking)

Hey, thanks for the reply. I did that yesterday and I think I got it right.

The answer you put is incorrect. It is the reciprocal of that.

[tex]\frac{(2w-3)(2w+3)^2}{6}[/tex]

You can test any simplification or expansion/contraction problem by assigning the variable an arbitrary value, then solve for the original equation and then your result.
