#-21r^2-56r#

You would basically multiply #-7r# with both #8# and #3r#:

#-7r(8) + -7r(3r)=#

#-21r^2-56r#

#-21r^2-56r#

We need to "distribute" the #-7r# to both terms in the parenthesis. This is done with multiplication.

We can essentially rewrite this expression as

#-7r(8)-7r(3r)#

Notice, we have "distributed" the #-7r#. We now multiply to get

#-21r^2-56r#

Hope this helps!
