See the entire simplification process below:

Explanation:

First, expand the terms in parenthesis by multiplying each term within the parenthesis by the term outside of the parenthesis, #color(red)(7)#:

#2 + (6m + 3)color(red)(7) ->#

#2 + (color(red)(7) xx 6m) + (color(red)(7) xx 3) ->#

#2 + 42m + 21#

Now group like terms and then combine like terms to complete the simplification:

#42m + 21 + 2 ->#

#42m + 23#
