The first term in the expansion will have the (3p) term to the 9th power.
The second term will have the (3p) term to the 8th power, and the (-2/p) term to the first power, resulting in a term with p to the 7th power.

Continuing that analysis we can see that the term in the expansion containing p to the first power must use the (3p) term 5 times and the (-2/p) term 4 times.

Then using binomial expansion, the term containing p in the expansion is
