Question

Rewrite this expression with grouping symbols:

5m + 5n

Answer 1

5(m+n)

Explanation:

Parenthesis are grouping symbols and can be used to separate factors like 5(m+n). The factor which 5m and 5n share in common is 5. This is called the greatest common factor since it multiplies into each term. It can be removed from each term and written as 5(m+n).
