Answer:
3c^3+2c^2-15c-14

Explanation:

First, start out by multiplying two of the quantities together. I began with multiplying (3c-7) and (2+c)


(3c-7)(2+c)\\\\=6c+3c^2-14-7c\\\\=3c^2-c-14

Then, you multiply that answer by (c+1)


(3c^2-c-14)(c+1)\\\\=3c^3+3c^2-c^2-c-14c-14\\\\=3c^3+2c^2-15c-14
