When multiplying monomial by a binomial we use Distributive Property of Multiplication.
When multiplying binomial by a binomial we use FOIL(First,Inner,Outer,Last) Method.
When multiplying sum and difference of two binomials we just square the first term and multiply the last terms.

No what I mean is, the other terms except for FOIL and dist. are there other patterns?
Yes, it if the product is a special product (e.g. Difference of Two Squares,Prefect Square Trinomial, Cube of a Binomial)
