I was born and grown up on the poor land in Duc Tho district, Ha Tinh province. That’s where deeply attaches to me 24 years of life. If anyone who asks me that “What’s the thing your most proud of?” .I will answer that’s my hometown. Duc Tho is the land poor where the people live by rice cultivation, breeding, and fishing. Although the life is very difficult, but the people is very friendly, and studious. In Duc Tho, there is a Tung Anh village where called “Doctor village”. Duc Tho is also the home of Tran Phu Secretary General, and marked many memories of the great leader Ho Chi Minh.
If you come to Duc Tho, you will feel many interesting things, visiting Tran Phu tombstone, La Giang dyke, rowing on La driver, and enjoying the traditional songs. In the evening, they can enjoy a special food which is “mussel rice” – just only eat one time, you will never forget.
Beautiful and unobtrusive! Duc Tho always tries to grow, and to improve the life of people, but keeping the traditional culture.
Giải:
\(\left(x^2+\dfrac{1}{x^2}\right)-3\left(x+\dfrac{1}{x}\right)+4=0\left(1\right)\)
ĐKXĐ: \(x\ne0\)
Đặt \(x+\dfrac{1}{x}=a\)
\(\Leftrightarrow a^2=\left(x+\dfrac{1}{x}\right)^2\)
\(\Leftrightarrow a^2=x^2+2+\dfrac{1}{x^2}\)
\(\Leftrightarrow a^2-2=x^2+\dfrac{1}{x^2}\)
Ta có phương trình:
\(\left(1\right)\Leftrightarrow a^2-2-3a+4=0\)
\(\Leftrightarrow a^2-3a+2=0\)
\(\Leftrightarrow a^2-2a-a+2=0\)
\(\Leftrightarrow a\left(a-2\right)-\left(a-2\right)=0\)
\(\Leftrightarrow\left(a-2\right)\left(a-1\right)=0\)
\(\Leftrightarrow\left[{}\begin{matrix}a-1=0\\a-2=0\end{matrix}\right.\)
\(\Leftrightarrow\left[{}\begin{matrix}x+\dfrac{1}{x}-1=0\\x+\dfrac{1}{x}-2=0\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x+\dfrac{1}{x}-1\ne0\\x=1\left(TM\right)\end{matrix}\right.\)

Teacher plays an important role in every child’s soul. To me, miss Dung-my head teacher. She taught literature from grade 10 to 12. She is tall, young, slim body with round face and bright smile. She is a devoted and responsible teacher as she always prepares carefully all the lessons before going to class. She teaches us the way to love people and becoming a good citizen for the country. Moreover, student love the way she teach, mark the score and correct the mistake. In my opinion, she is not only my teacher but she also works as my second mother at school. She helps student through thick and thin in life. Whenever facing up with any problem, I have no hesitation to share with her then she finds out the best solution or gives me some helpful advice. Additionally, if we don’t attend the class for some reasons, she immediately contacts us and asks whether we are fine. It seems that she spend her youth to learn and give deep knowledge to young generation and she really enjoys the job. Most of the time she spend for taking care of children from education to daily life. She is one of my idols because of her talent, personality and career. Therefore, almost student look up to her and thank her for kindness and responsibility.
