Comment factoriser A B 2 ?
Pour factoriser, on utilisera les mêmes formules, mais dans le sens inverse : (a+b)² = a² + 2ab + b² (a-b)² = a² - 2ab +b²
Quelle est la formule de A B au carré ?
L'égalité (a+b)² = a² + 2ab + b² est la première que l'on retrouve dans le livre II des Éléments d'Euclide.
Comment calculer a2 +b2 ?
a2 - b2 = (a - b) (a + b)
L'aire du rectangle allongé est donc égale à la différence des aires de côtés a et b.- Les trois formules suivantes sont à retenir : F1 : (a + b)2 = a2 + 2 × a × b + b2.
