Double Distributivity and Factorization
This page delves deeper into mathematical operations, introducing factorisation and double distributivité - exercices corrigés.
Factorization is defined as the process of transforming a sum or difference into a product. An example is provided: 7x + 42 = 7(x + 6), demonstrating how common factors can be extracted.
Definition: Factorizing an expression means transforming a sum (or difference) into a product.
The concept of double distributivité is then introduced, with the general formula (a + b)(c + d) = ac + bc + ad + bd. This formula shows how to expand the product of two binomials.
Vocabulary: Developing a product means transforming it into an algebraic sum.
The page emphasizes the importance of following the rules of signs when distributing in each product. This is crucial for correctly applying the double distributivité formule.
Highlight: When using double distributivity, it's essential to respect the sign rules while distributing each term.
