Question

What is the sum of the “outer” and “inner” products as described in the FOIL method when multiplying (x + 5)(x - 6)?

Answer 1

The "outer" terms are x and -6, so their product is -6x.
The "inner" terms are +5 and x, so their product is 5x.
The sum of "outer" and "inner" terms is -6x +5x = -x. (selection B)
