Question

The following factors are not prime: (x2- 7x)(7x+21).What remains to be factored? (can be more than one answer). A) Factor out the 7x from the product. B) Factor out an x from the first binomial. C) Factor out a 7 from the second binomial

Answer 1

C
The first binomial can have an x factored out, resulting in (x-7) and the second binomial can have a 7 factored out, resulting in (x+3)

Answer 2
