Bonsoir,
Si je soustrais 10 à un nombre son carré est diminué de 1000.
N : nombre
(N - 10)^2 = N^2 - 1000
N^2 - 20N + 100 = N^2 - 1000
20N = 1000 + 100
20N = 1100
N = 1100/20
N = 55
Vérification :
55 - 10 = 45
45^2 = 2025
55^2 = 3025
3025 - 2025 = 1000
5) aire du carré a) :
Ac = (x + 1)(x + 1) - 1 * 1
Ac = (x + 1 - 1)(x + 1 + 1)
Ac = x(x + 2)
Aire du rectangle b) :
Ar = x(x + 2)
Donc Ac = Ar
