Example Question #2 : How To Use The Grid Method For Foil
Multiply:
To multiply two binomials, both terms in the first binomial need to be multiplied with both terms in the second binomial. A good way to make sure that all of the pairs are multiplied is to set up the box/grid:
In each empty box, multiply the intersecting terms:
Now, combine like terms. -6x and 4x are both terms with x, so we can add them to be -2x.
Final answer:

The answers are the same.
The answers are completely different.
The answers are the same except that the middle terms are different.
The answers have opposite signs.
The answers are the same.
Let's look at the grid for 
Now let's look at the grid for 
Top left corner:
Both grids give us 
Top right corner:
Bottom left corner:
Bottom right corner:
