Bonjour ! ;)
Réponse :
Exercice 41 :
A = 2 * n + 2 * 7
A = 2 [n + 7]
B = 2 * n + 5 * n
B = n [7]
C = 10 + n * 10
⇔ C = 1 * 10 + n * 10
C = 10 [1 + n]
D = 9 * n - 15
⇔ D = 3 * 3n - 3 * 5
D = 3 [3n - 5]
E = n * 6 - 8 * n
⇔ E = 6 * n - 8 * n
E = 3 * 2 * n - 4 * 2 * n
E = 2n [3 - 4]
F = n * n - 5 * n
F = n [n - 5]
G = 24n - 24
⇔ G = 24 * n - 24 * 1
G = 24 [n - 1]
H = 12n * n + 2 * n
H = 6 * 2 * n * n + 2 * n * 1
H = 2n [6n + 1]
