Example Question #186 : Distributive Property
Using the grid method, find the product of 
Using the grid method is an alternate way of doing FOIL. This utilizes the "tic tac toe" grid. Upon creating the grid, we need to write in the binomials we were given to multiply. Such is done like so:
Using the same principle, the left bottom box will be completed by multiplying 
The remaining boxes in the rightmost column may be solved using the same principle that was used to solve for the middle column. The filled out grid will look like this:
The problem is nearly done. All that is left for us to do is to write this as a mathematical expression and collect like terms. Completing this step will yield us our final answer.
Note that this last step only requires the values from the four boxes we solved for.
