\(x^2+2x+9⋮x+2\)

\(\Leftrightarrow x\left(x+2\right)+9⋮x+2\)

Dễ thấy \(x\left(x+2\right)⋮x+2\) nên \(9⋮x+2\)

\(\Rightarrow x+2\in\left\{1;9;-1;-9;3;-3\right\}\)

\(\Rightarrow x\in\left\{-1;7;-3;-11;1;-5\right\}\)

8) Nói về thú cưng: 

Everyone has one’s favorite pet. As for me, I very love my dog named Pull. The dog is an Alaska dog with straight brown hair, blue eyes and big ear. He is said to be intelligent, loyal and obedient. Moreover, Pull is friendly and well-trained when I said “sit down” or “run around” he will do absolutely true. I remember the first day I have met Pull-my 12 birthday, he is a present given by my father. At that time, Pull was 2 years old, he was small and unfamiliar with my family’s members. Nowadays, he is an adult dog with good health and he seems to be one important member of my whole family. Pull and I usually have wonderful time together we eat, go shopping, walk in the sunrise and sunset, and play in a local park. As I’m the only child in my family, Pull is my best friend. Whenever I have trouble or whatever mistake I do, I always have him by my side. Although he is not able to talk, I feel the love and caring of him for me. Besides, Pull helps my mother much in household, he can hold a heavy bucket of water. Dog is not food; therefore I condemn the action of stealing dog by killing them with electricity in VN and selling it for some taverns. Dog is an animal for people to feed, love and care. Dog is not a product of any individual who wants to earn illegal money from it. Finally, it’s better for a house with a domes dog so that it brings happiness in addition to keeping your house save.

My family consists of 4 people: my parents, my older brother and I. My brother’s name is Hoang. He is 25 years old, 3 years older than me. He works as an engineer in a multinational group in HCM city. He is tall, bright skin, handsome face with charming smile and brown eyes. My brother and I have mutual understanding with each other. Not only in studying, he also helps me through many ups and downs in all aspects of life. In my opinion, he is my hero when I face up with problems, he finds out the best solution. During childhood, we go through lots of happy and unforgettable time to play as 2 stubborn kids. It maintains vivid memory about my brother. His hobby is collecting stamps and he seems to enjoy it so much. He s rap, hip-hop music and horror movie. At weekend, he usually hangs out with friends, watches movie in cine. In freetime, he spends time reading romance book, playing chess with father and planting his own cactus. Besides, he is a member of a local sport club, he plays as a footballer every afternoon. He is a kind, friendly person but a little lazy. Therefore, I usually have to tidy up his room and his office. However, I often look up to my brother for many successful things he acquire; for his brave and kindness.

My favorite little sister is Linh. She is sixteen years old. She is tall, 1 meter and 60 centimeters tall. She has long wavy, shiny, black hair. Her skin is so beautiful. It reminds me of the color of coffee with milk. Her face is a heart form. You can see her anger or happiness in her big expressive brown eyes. She has a little nose, and her mouth looks it was painted light pink. She can speak two thousand words, moving from hate to love and from love to hate, change her opinion five times, start talking alone, forget what she was talking about at the beginning, all in one minute. It’s a little difficult to try to talk to her, but it’s fun. She has a strong personality. She falls in love every year, and she is a little crazy, but I love her personality. Sometimes I want to kill her, and she wants to kill me too. I think that is normal between sisters. She is the song “Faded” by Alan Walker. She s rap, hip-hop and pop music. She s reading romance and fantasy books. She enjoys horror movies (I know, she is crazy). She loves to go out with her friends, paint her nails, and wear high heel shoes. She is always dancing, studying, reading, working and going out. She is a very busy girl. The truth is that since childhood, she has danced, sung and talked incessantly. She always knew what she wanted and never hesitated to say her opinion. She has lived happy and sad moments everyone, but she has continued with her life. She makes me feel very proud for that reason. She will continue to grow up to become “the best version of herself,” and work hard to pay my bills (It’s a family joke). When she reads this part she will want to hit me. I love my teen sister.
 

Ý của em là viết các paragraph ngắn đúng không?  Chị nghĩ em nên dựa vào các đoạn văn đã học trong sách thay những từ ngữ phù hợp và tham khảo thêm trên google, với lại chị chân thành khuyên em là em hãy viết đơn giản, dễ hiểu, đúng sự thật hoặc có chút văn chương để đoạn văn được hay, chứ đừng chép y nguyên bài của người khác khó nhớ lắm và cũng đừng dịch trên google translate dễ sai ngữ pháp lắm! Vậy nha!

Chúc em học tốt!!!!!!!^_^

I only have one sentence that is: 'I don't have a lover'.

"In my dream, in my dream, in my dream,..."

My favourite meal is the breakfast. Almost everyday I wake up early, so I cook two eggs and prepare a delicious coffee black. I get my breakfast alone, but I don't matter with it.

        I still call An Duc Secondary School my second home. It is located in An Duc Village, Quynh Phu District, Thai Binnh Province. Although my school is not very large, it is very spacious and clean and beautiful. The school gate is very tall and spacious, and on both sides of the corridor are flower beds leading directly to the school yard and the classrooms. The school yard is quite large, around the yard are ancient eagle and phoenix trees covered in shade, with flower beds and green grass. Under the trees are rows of benches for us to read and talk after each class. The classrooms are fully furnished with desks and chairs, a cupboard for study supplies and a corner for displaying beautiful articles and articles. In addition, my school also has other classrooms such as music room, computer room, library, English classrooms ... I love my school very much. One day, I will walk away from this school, but I will always remember it along with the beautiful memories it brings.

Hi everybody. Today I would like to talk about my school. Let's start! My junior high school really is like a paradise with fresh air, picturesque surroundings and lovely people beside me. The school is located in the countryside among the immense green fields. Simple design with two buildings perpendicular to each other and many shade trees and flowers give me a feeling of closeness. Besides, there is a vacant lot for students to play football in the afternoon after school. Moreover, all the teachers are wholeheartedly and devoted. In addition, I have close friends who are always with me and help me whenever I have a problem. In short, the school has left a very beautiful impression of my childhood experiences and the memories of the school will never fade in my thoughts. Oh! I really love it...
