Ta có \(\frac{4n+21}{2n+3}=\frac{4n+6+15}{2n+3}=\frac{4n+6}{2n+3}+\frac{15}{2n+3}=\frac{2\left(2n+3\right)}{2n+3}+\frac{15}{2n+3}=2+\frac{15}{2n+3}\)

\(\Rightarrow2n+3\inƯ\left(15\right)=\left\{1;3;5;15\right\}\)

Nếu 2n + 3 = 1 thì 2n = - 2 <=> n = - 1 (loại)

Nếu 2n + 3 = 3 thì 2n = 0 <=> n = 0 (nhận)

Nếu 2n + 3 = 5 thì 2n = 2 <=> n = 1 (nhận)

Nếu 2n + 3 = 15 thì 2n = 12 <=> n = 6 (nhận)

Vậy n \(\in\) {0;1;6}
