Vì n + 5/n + 2 có GT nguyên
Nên n + 5 chia hết cho n + 2
n + 2 + 3 chia hết cho n + 2
Mà n + 2 chia hết cho n + 2
Nên 3 chia hết cho n + 2
n + 2 thuộc U(3) = {-3 ; -1 ; 1 ; 3}
n thuộc {-5; -3 ; -1 ; 1}
Để n+5/n+2 có giá trị nguyên
=>n+5 chia hết cho n+2
=>n+2+3 chia hết cho n+2
Mà n+2 chia hết cho n+2
=>3 chia hết chon n+2
=>n+2 thuộc Ư(3)={-3;3;-1;1}
Ta có bảng sau
| n+2 | -3 | 3 | -1 | 1 |
| n | -5 | 1 | -3 | -1 |
| Vậy n thuộc {-5;1;-3;1} |
