Factorisation: De la somme au produit
Factorisation: On peut factoriser l'expression (a + 3) - (4a - 5) (a + 3) en utilisant la distributivité. En simplifiant, on obtient E = (a + 3) (-2a + 4).

Multiple Choice
What is the result of factorising the expression (a + 3) - (4a - 5) (a + 3)?
-2a^2 - 2a + 12
-2a^2 + 2a - 12
-2a^2 + 2a + 12
-2a^2 - 2a - 12
7
Factorising Expression
Trivia: Factorising the expression (a + 3) - (4a - 5) (a + 3) results in -2a^2 + 2a + 12. This expression can be simplified by distributing the negative sign to both terms inside the parentheses and combining like terms. The resulting quadratic expression has a leading coefficient of -2 and a constant term of 12.

Factorisation: De la somme au produit
Méthode 1: L'aire de la surface colorée est (a - b)².
Méthode 2: L'aire de la surface colorée est a² - 2ab + b².
Cours: Identité remarquable n°2
Activité 3: (a + b)(a - b)
On assemble deux trapèzes rectangles identiques pour calculer l'aire totale.

Multiple Choice
What is the area of the colored surface in the given activity?
(a - b)²
a² - 2ab + b²
a² + 2ab + b²
a² + b²
10
Area Formula: a² - 2ab + b²
Trivia: The formula a² - 2ab + b² represents the area of the colored surface in the given activity. It is derived from the expansion of (a - b)², which simplifies to a² - 2ab + b². This formula is commonly used in algebra to calculate the area of a square or rectangle with side lengths a and b.
