#48x^2-38x-21#

Use F.O.I.L. This stands for First, Outside, Inside, Last.

1) Find the product of the First terms, #6x# and #8x#, which is #48x^2#

2) Find the product of the Outside terms, #6x# and #3#, which is #18x#

3) Find the product of the Inside terms, #-7# and #8x#, which is #-56x#

4) Find the product of Last terms, #-7# and #3#, which is #-21#

5) Add all of these together, forming #48x^2+18x-56x-21#

6) Simplify it, making #48x^2-38x-21#
