Multiplying Polynomials: Key Concepts and Techniques

Why can't the FOIL method be used for multiplying a binomial by a trinomial?

• Because FOIL can be used for any polynomial multiplication.

• Because FOIL is exclusively for binomial by binomial multiplication.

• Because FOIL only applies to trinomial by trinomial multiplication.

• Because FOIL is a simplified version of the distributive property.
