Tet is a national and family festival. It is an occasion for every Vietnamese to have a good time while thinking about the last year and the next year. At Tet, spring fairs are organized, streets and public buildings are brightly decorated and almost all shops are crowded with people shopping for Tet. At home, every is tidied, special food is cooked,offerings of food, fresh water, flowers and betel are made on the family altar with burning joss- sticks scenting the air. First-footing is made when the lucky visitor comes and children are given lucky money wrapped in a red tiny envelope. Tet is also a time for peace and love. During Tet, children often behave well and friends, relatives and neighbors give each other best wishes for the new year.

\(Đặt A=(n^4-3n^3+n^2-3n+1):(n^2+1) \)

\(=(n^4+n^2-3n^3+n^2-3n+10):(n^2+1)\)

\(=[n^2(n^2+1)-3n(n^2+1)+1]:(n^2+1)\)

\(=[(n^2+1)(n^2-3n)+1]:(n^2+1)\)

Để A thuộc Z thì tử phải chia hết cho mẫu mà\((n^2+1)(n^2-3n) \) chia hết cho \(n^2+1\)

=> 1 chia hết cho \(n^2+1\)

=> \(n^2+1\) thuộc Ư(1)

mà \(n^2+1>=1\) (với mọi n)

=>\(n^2+1=1\)

=>n=0

Some people say they prefer eating at restaurants to eating at home because they think they can save time spending to cook meal to do other things. However, in my view, I prefer to eat at home. For the following reasons I have three reasons explain why I think this way. First, eating at home helps you save money. Second, hardly any restaurants sever foods as healthy as those you prepare at home. Third, eating at home helps us have chances to get close to our family.

The first reason is that I can save money when eating at home. When you go to a restaurant and order dishes, look at the price on the menu and do a small calculation, you can see the price in the restaurant is at least twice higher than those you cook at home. Beside they are not delicious as food you cook at home. For example, the fried rice I order in restaurants have the price equal to those I spend to by material and make enough fried rice for the whole family. This explains for my first reason – eating at home help, you save money.

The second reason is that the food you prepare at home is healthier than those which are severed in restaurants. Compared with the soup you order at restaurants, the other one you make at home is healthier and more hygienic. For example, the soup I cook at home have more vegetables, meat, eggs, crabs, etc while those at restaurants just have little meat, crabs and vegetable, which is not enough nutrition for a person.

Third, the eating time with family is importance. It helps the family get closer. Imagine the scene of a family with mother and children cooking dinner together at weekend. They are cooking and telling the other person about their day at school or at work. Children learn how to make their favorite dishes. Father helps prepare the table and tell a joke to make the whole family laugh and bring the happy atmosphere to their house. This is one of the points that makes the house become home.

In conclusion, I prefer eating at home to eating at restaurants because of the reasons mentioned above.
