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.
Thanks,
EE
The answer you put is incorrect. It is the reciprocal of that.
[Math]\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.
