The Attempt at a Solution

the only term I think I understand is the -3<x-0>^0 but I'm not sure of the rest

It's not clear from the attached image. There are no terms in red.

In any event, you need to understand how the particular singularity function is defined. The link below is a slide show which has the definition of a singularity function and includes some examples of how distributed loads, etc. can be represented.

I read the slides but I'm still confused about this kind of distributed load

could you explain the contribution of each term?
