#1**+1 **

I basically expanded everything out.

\(120v^{18}-540u^{3}v^{13}-80uv^{15}+810u^{6}v^{8}+360u^{4}v^{10}-405u^{9}v^{3}-540u^{7}v^{5}+270u^{10}\)

hmmm...there is no u^2v^9 term.

So the coefficient is just 0.

So 0 is our answer.

Thanks! :)

I know there are smarter ways to do it...but I'm not smart...as my name suggests

We could simply just take a look at the factors.

\((2u - 3*v^3)*5*(3u^3 - 2v^5)^3\) never has a term for v^9, so it's impossible.

We can easily tell, but ummm...yeah....

XD :)
