Question

Which is a complete list of factors of each term in the expression

Answer 1

A factor is one part of a product.

In the given expression first we separate the terms.

here we have two terms: 15 and 20x

factors of first term 15 : since just one number is there so factors of 15 would be 1, 3, 5 and 15

factors of second term 20x: product of 20 and x gives 20x, so factors of 20x are 1,2,4,5, 10,20 and x

Answer 2

The correct answer for this problem is:

A) 15:1,3,5,15 and 20x: 1,2,4,5,10,20,x

This is correct because to be a complete list of factors for each term there has to be the most common factors but also has to have the variable, being x.
