Question

Expand and simplify (3c-7)(2+c)(c+1)

Answer 1

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`
