WebbSimplifying, we get 4x2 + 8x − 8 0(mod 83). Since 4 is coprime with 83 we can divide by 4 to get x2 + 2x − 2 0(mod 83). Hence x = −2 12 2 and so x = −1 3 . We need to find the … WebbDivisibilité et congruences. 1. Division euclidienne. Définition. Soient a a a et b b b deux entiers relatifs tels qu'il existe un entier relatif k k k tel que a = b k a=bk a = b k. On dit alors que : b b b divise a a a; b b b est un diviseur de a a a; a a a est un multiple de b b b.
