Explanation
We are given the expressions:
[tex]\begin{gathered} 4m+16 \\ -m+3 \end{gathered}[/tex]We are required to find the product of these expressions.
This is achieved as:
[tex]\begin{gathered} (4m+16)(-m+3) \\ 4m(-m+3)+16(-m+3) \\ -4m^2+12m-16m+48 \\ -4m^2-4m+48 \end{gathered}[/tex]Hence, the answer is:
[tex]-4m^2-4m+48[/tex]
