Merge partitions into a single one

Hello,

While attempting to install windows 10 on my Mac using Bootcamp in Mac OSX Mojave, it got stuck on "please wait while boot camp assistant is removing the partitions it created". I then followed the instructions on the thread

Stuck on "please wait while boot camp assistant is removing the partitions it created"

However, after this, I still have two partitions. I would like to merge them into a single partition in order to attempt installing windows 10 again. If it solves the problem, I'm willing to restore to factory settings since the computer is brand new and I haven't installed much else on it (How is this done?)

When I run diskutil list, I get:
