  skos:definition """En mathématiques, le développement d'une expression est un procédé inverse de la factorisation, de portée toutefois plus limitée que celle-ci : alors qu'on parle de factorisation aussi bien pour les nombres entiers que pour les polynômes, par exemple, on ne parle pas de développement des nombres entiers ; cette notion nécessite en effet de travailler dans une algèbre. À l'issue d'un développement, on obtient une forme dite forme développée.

Expansion of a polynomial expression can be obtained by repeatedly replacing subexpressions that multiply two other subexpressions, at least one of which is an addition, by the equivalent sum of products, continuing until the expression becomes a sum of (repeated) products. During the expansion, simplifications such as grouping of like terms or cancellations of terms may also be applied. Instead of multiplications, the expansion steps could also involve replacing powers of a sum of terms by the equivalent expression obtained from the binomial formula; this is a shortened form of what would happen if the power were treated as a repeated multiplication, and expanded repeatedly. It is customary to reintroduce powers in the final result when terms involve products of identical symbols.
