My name is Duc and I’m a Vietnamese. I am twenty-four years old. I live in Ha Noi in the south of Vietnam.
I have a big family with six people. I have two sisters and a brother. My sisters are older and my brother is younger than me. My father is a teacher at a secondary school. He has worked for 35 years in the field and he is my biggest role model in life. My mother is a housewife. She is nice and she is really good at cooking. I love my family so much.
I’m a generous and easy-going person but when it comes to work I’m a competitive perfectionist. I’m also an optimis and outgoing person so I have many friends and other social relationships. I enjoy reading, writing and doing math. I decided to become a Civil Engineer because I have always been fascinated by bridges, buildings, and skyscrapers. A degree in Civil Engineering enables me to achieve my goals and also gives me an opportunity to make a difference in the community.
Five years from now, I want to become a project manager of a construction project. As a project manager, my primary goals are managing people, set budgets, and making decisions of all kinds. I also want to speak English fluently so I can work with people from different countries.

\(a)\) Để A là phân số thì \(n-5\ne0\)
\(\Rightarrow\)\(n\ne5\)
Vậy để A là phân số thì \(n\ne5\)
\(b)\) Ta có :
\(A=\frac{n+2}{n-5}=\frac{n-5+7}{n-5}=\frac{n-5}{n-5}+\frac{7}{n-5}=1+\frac{7}{n-5}\)
Để A có giá trị nguyên thì \(\frac{7}{n-5}\) phải có giá trị nguyên
\(\Rightarrow\)\(7\) chia hết cho \(n-5\)
\(\Rightarrow\)\(\left(n-5\right)\inƯ\left(7\right)\)
Mà \(Ư\left(7\right)=\left\{1;-1;7;-7\right\}\)
Suy ra :
| \(n-5\) | \(1\) | \(-1\) | \(7\) | \(-7\) |
| \(n\) | \(6\) | \(4\) | \(12\) | \(-2\) |
Vậy để A có giá trị nguyên thì \(n\in\left\{-2;4;6;12\right\}\)
