Composition
The combination of two Functions to form a single new Function. The composition of two functions
and 
is denoted 
and is defined by
when
and are both functions of 
.An operation called composition is also defined on Binary Quadratic Forms. For two numbersrepresented by two forms, the product can then be represented by the composition. For example, the composition of the forms
and 
is given by 
, and in this case, the product of 17 and 13 would be represented as(
). There are several algorithms for computing binary quadratic form composition, which is thebasis for some factoring methods.
