Simplify using a table.
(5w+2)(8w+5)

Hence, the simplified expression is:

40w^2+41w+10

We have to simplify using a table to simplify the term:

(5w+2)(8w+5)

i.e. this is evaluated as:

              5w               2

8w        40w^2       16w

5          25w             10

The value in the table are obtained by multiplying each of the row entry with the corresponding column entry and hence the final result is the addition of all the entries.

Hence we obtain a expression as:

(5w+2)(8w+5)=40w^2+16w+25w+10

                     =40w^2+41w+10

Hence, the expression is:

40w^2+41w+10
