The second term of the expansion (3x-4y)^5 is

To solve this, we're going to have to use the binomial theorem. It states that:

If you want a specific term, we can just disregard the polynomial and use this:

Where A_k is the kth term. In the context of this problem it would look like:

So, based on that, our second term is
