1- vérifier que U+V est divisible par 10 lorsque n= 12 ou que n=13
2-(a) Réduire U+V
(b) mettre 10 en facteur dans U+V

Bonsoir,
On a :
U = 7n²-9n+5 et V =3n²-n+5
1- n = 12
U(12) = 7×12²-9×12+5 = 905
V(12) = 3×12²-12+5 = 425
U(12)+V(12) = 905 + 425 = 1330
1330/10 = 133
Faire la même methode pour U(13)+V(13)
2-(a) U+V = 7n²-9n+5 + 3n²-n+5 = 10n²-10n+10
(b) U+V = 10n²-10n+10 = 10(n²-n+1)
(c) Tous les résultats de U+V sont divisibles par 10.
Bonne soirée !
