Question

Explain how you can use the distributive property to check the binomial factors when a trinomial has been factored. Include an example in your explanation.

Answer 1

You use FOIL (first, outer, inner, last) to check your answer. Eg: (x-4)(x+3)then distribute by using FOIL to get    2                                                     2
                                                  x   +3x -4x -12 then simplify to get x   -x -12
